Summary
This recap covers two related events from January 2026: (A) panel discussion in five parts and (B) privacy-enhancing technologies in digital advertising. What emerges from both is a central challenge: (C) looking ahead, enforcement must catch up with innovation, and regulators must understand the technical realities they aim to govern. On Data Protection Day 2026, Rob van Eijk (Future of Privacy Forum) moderated a panel examining whether regulatory frameworks can effectively address the rapidly evolving online tracking landscape. The European Data Protection Supervisor (EDPS) and the Council of Europe organized the event. The panel brought together Rosa Barcelo (McDermott Will & Emery), Itxaso Domínguez de Olazábal (EDRi), and Cristiana Teixeira Santos (Utrecht University). The discussion surfaced fundamental tensions in Europe's approach to digital privacy. You can watch the panel recording on YouTube .
During the same week, the Lisbon Council hosted a High-Level Working Lunch examining privacy-enhancing technologies in digital advertising. The invitation-only gathering brought together stakeholders from industry, civil society, and regulators. Participants explored whether PETs represent a workaround to privacy rules or a path forward for European competitiveness.
Key Takeaways
Data Protection Day 2026 Panel
- The Digital Omnibus proposal risks creating a patchwork framework that shifts privacy protections toward a GDPR-centric model, potentially weakening specific safeguards for terminal equipment access
- Analytics exemptions create loopholes for invasive tracking technologies that collect granular behavioral data (URLs, scrolling, key presses, mouse positions) without consent
- One-click rejection buttons are largely cosmetic. Backend systems often fail to register or respect user decisions, continuing data collection despite rejection
- The problem is not lack of rules but lack of enforcement. Regulators need to work with computer scientists to audit the tracking stack and verify backend compliance
- Server-side tracking operates seamlessly on servers rather than browsers, making it harder to detect or block compared to traditional client-side cookies
Lisbon Council Working Lunch
- Privacy-enhancing technologies represent both a potential workaround to privacy rules and a path forward for European competitiveness
- Bottlenecks in the PETs ecosystem require examination of incentives needed to drive adoption while safeguarding personal data
- PETs are positioned as strategic innovation enablers beyond mere compliance tools in one of the fastest-growing data protection markets
Both discussions converge on a common challenge. Europe's regulatory framework stands at a crossroads. The Digital Omnibus choices will determine whether the consent-first principle remains the cornerstone of digital privacy or gets diluted by exemptions and technological realities the original frameworks never anticipated. The path forward requires enforcement courage, technical expertise, and innovation that respects fundamental rights.
A: Data Protection Day 2026 Panel on Online Tracking Regulation
Van Eijk structured the panel around five interconnected themes that together reveal a regulatory landscape struggling to keep pace with evolving tracking technologies.
What Problem Is the Proposal Trying to Fix?
Van Eijk opened by noting Europe has spent over two decades trying to get cookie regulation right. From the original ePrivacy Directive in 2002, through the failed ePrivacy Regulation negotiations, to today's Digital Omnibus proposal packaged as simplification. He asked Domínguez de Olazábal what exactly the proposal is trying to fix.
Domínguez de Olazábal opened with a sharp critique. Civil society expected the outcome might be a hybrid text combining different regulations. Instead, the Digital Omnibus arrived as a supposed solution claiming to fix ePrivacy. She warned the proposal represents deregulation that shifts protections toward a GDPR-centric model based on legitimate interest. This undermines the confidentiality of communications and specific safeguards for accessing terminal equipment.
The Shift in Legal Framework
Van Eijk bridged to the legal architecture. The proposal positions itself as simplification, but that framing is contested. He asked to unpack what's actually changing, starting with the consent-first principle central to ePrivacy. He then asked Barcelo whether the proposed amendments improve the business position and if the proposal strikes the right balance, noting that the Commission Staff Working Paper identifies Article 5.3 as causing substantial burden for businesses.
Barcelo offered a contrasting business perspective, viewing the proposal as reasonably balanced and an evolution rather than a revolution. She noted that many proposed exceptions for security and analytics already reflect current practice by Data Protection Authorities in France and Germany. The changes create legal certainty through harmonization, though she warned this comes with a trade-off: fines will be harmonized upward to GDPR levels rather than the currently variable national penalties.
Analytics Exemptions Create Tracking Loopholes
Van Eijk bridged to the next theme. The proposal shifts the legal framework and attempts to balance business needs with user control. But much of the debate hinges on the exceptions carved out from consent requirements. He asked Santos whether the proposal changes anything for analytics and requested practical examples of first-party tools that may conflict with confidentiality principles.
Santos delivered a detailed technical critique of the proposed analytics exemptions under Article 88a, paragraph 3c. The exemptions claim to limit collection to aggregated information for website operation. She warned these exemptions create loopholes for highly invasive tracking.
She cited widely-used audience measurement services as concrete examples. These tools collect granular behavioral data including URLs visited, time spent, scrolling actions, key presses, mouse positions, browser and OS types, screen resolution, language, and IP addresses. This data is highly identifiable. Yet the new proposal could exempt it from consent requirements.
Server-side tracking allows this data collection to happen directly on the server rather than the browser, making it seamless and harder to detect or block compared to traditional client-side cookies. Tools appear as standard first-party communication while collecting vast amounts of user behavior data.
The Cosmetic Compliance Problem
Van Eijk shifted focus. After discussing what requires consent and what doesn't, he turned to how consent actually works in practice. He asked Barcelo about the main challenges in standardizing machine-readable consent signals, then asked Santos about one-click rejection, dark patterns, consent fatigue, and backend compliance gaps.
The panel dissected why current consent mechanisms fail in practice. Santos described one-click rejection buttons as largely cosmetic. User studies show that even when reject buttons exist, dark patterns nudge users toward acceptance. Shiny accept buttons contrast with dull reject buttons. Negative framing scares users by suggesting they'll lose site functionality if they reject cookies.
More critically, the visual interface is only half the problem. Empirical research shows a frontend versus backend disconnect. Even when users successfully click reject or revoke consent, the backend often ignores these decisions. Systems fail to record choices correctly. Data collection continues. Systems don't communicate decisions downstream to third-party ad-tech actors.
Domínguez de Olazábal added that the proposed exemptions undermine privacy signals like Global Privacy Control. If companies receive broad exceptions for media or audience measurement, they simply won't respect the user's signal to reject tracking. This renders the mechanism useless. Barcelo questioned how a single browser signal could satisfy GDPR's requirement for specific, granular consent. GDPR requires separating analytics from marketing consent. A single signal cannot achieve this without compromising functionality for users.
Van Eijk observed that ePrivacy problems are dealt with in a fragmented landscape. Nudging is addressed in the Digital Services Act but applies to only a few actors. The Digital Fairness Act will extend some of these problems to B2B relationships. A much larger number of organizations will be subject to these new rules.
Enforcement Over Legislation
Van Eijk framed the final theme around technical neutrality and future-proofing. He noted that the discussion had assumed regulators understand the technologies they're regulating. But the tracking landscape has moved far beyond cookies. He asked Santos what new tracking technologies the proposal needs to contend with.
A recurring theme throughout the panel was the problem isn't a lack of rules, but a lack of enforcement. The panelists emphasized that new legislative frameworks won't solve tracking problems. Regulators must enforce existing bans. Regulators must audit technical compliance.
Closing Recommendations
Van Eijk gave each panelist one final opportunity. If you had one message for policymakers working on this proposal, what would it be?
Santos closed with a recommendation to policymakers. Regulators must work directly with computer scientists. The law cannot be effective if policymakers don't understand the technical reality of tracking. This includes server-side tracking, fingerprinting, and the backend tracking stack. Regulators need standardized technical mechanisms to audit backend systems. These mechanisms must verify that backend compliance matches frontend user choices.
Domínguez de Olazábal stressed that policymakers should stop relying on company self-regulation. The focus must shift to strict enforcement of existing bans on tracking, rather than creating new loopholes or relying on cosmetic interface changes. Barcelo added that policymakers need courage to navigate this difficult legislative landscape while maintaining balance between business needs and user rights.
Audience Questions
Van Eijk bridged to audience questions by raising a question the Digital Omnibus doesn't address. What happens when the user isn't even making the decision? When AI agents shop, browse, and consent on our behalf, who is the user whose terminal equipment we're protecting? The ePrivacy framework assumes a human at the keyboard, but that assumption may have an expiration date.
The audience questions surfaced additional concerns beyond the panel themes. One question addressed whether Europe needs a parallel internet infrastructure with European endpoints for data sovereignty. Domínguez de Olazábal responded that while European alternatives like Mastodon exist, a European flag doesn't automatically mean safer data practices.
Another question raised the issue of data brokers selling tracking data to security services. Investigations revealed that agencies in the US and Europe purchase granular location data from brokers. Domínguez de Olazábal emphasized the lack of dedicated AdTech regulation and noted that the IAB's Transparency and Consent Framework has been ruled illegal. Santos pointed out that the US requires brokers to register and disclose their data practices, a requirement that doesn't exist in the EU. Van Eijk noted the risks, citing how abortion clinic location data purchased from brokers could have serious legal consequences.
Questions also covered whether Data Intermediaries from the Data Governance Act could relieve tracking fatigue, and whether AdTech business models are fundamentally illegal or simply misaligned with data protection rules.
B: Lisbon Council Working Lunch on Privacy-Enhancing Technologies
In a related session during the same week, the Lisbon Council hosted a High-Level Working Lunch on Privacy-Enhancing Technologies in Digital Advertising ( Lisbon Council event page , archived event page ). The invitation-only gathering brought together representatives from FEDMA, Microsoft, the European Commission, The European Consumer Organisation, Zalando, Mozilla, IAB Europe, the Future of Privacy Forum, and the European Data Protection Board.
The discussion explored whether privacy-enhancing technologies (PETs) represent a way around privacy rules or an important way forward for Europe's competitiveness. Participants examined the bottlenecks hindering the PETs ecosystem, the incentives needed to drive adoption while safeguarding personal data, and the real-world impact of PETs deployment.
Europe shifts toward new data protection provisions in the Digital Omnibus. Industry increasingly positions PETs not just as compliance tools but as strategic innovation enablers. PETs represent one of the fastest-growing markets in data protection.
C: Looking Ahead
The panel made clear that Europe's challenge isn't drafting better rules. The challenge is enforcing the ones we have. Server-side tracking proliferates. Analytics exemptions expand. Cosmetic compliance mechanisms multiply. The gap between what the law promises and what users experience continues to widen.
The discussions at Data Protection Day 2026 and the Lisbon Council working lunch highlight the same crossroads. Will the Digital Omnibus strengthen privacy protections through genuine enforcement and technical auditing? Or will it dilute them through exemptions and a shift away from the consent-first principle? This principle has defined European digital privacy for nearly two decades. The answer depends less on legislative language than on regulators' courage to audit backend systems. Regulators must hold companies accountable for what happens after users click reject.
