EU ruling: tracking-based advertising [...] across Europe has no legal basis

Original Article ↗ Hacker News Discussion ↗

An EU court has ruled that key parts of the online ad industry’s tracking framework, used by companies like Google, Amazon and Microsoft, lack a legal basis under GDPR because they rely on opaque identifiers and sham consent. Commenters argue this exposes the fundamental illegality and societal costs of surveillance-based advertising, while contrasting it with contextual ads that don’t require profiling users. Many are skeptical about enforcement given the small fines and slow process, but see the ruling as an important precedent that could force changes in how data is collected, shared and monetized across the web.

Critique of personalized tracking ads

  • Many see “personalized” ads as benefitting only ad networks: users lose privacy and attention, advertisers lose money in opaque auctions.
  • Common complaint: retargeting keeps pushing products already bought (cars, fridges), indicating crude signals and poor algorithms.
  • Some argue the real purpose is demographic and class segmentation (e.g. cheap vs luxury gyms), not user benefit.
  • Others describe the whole ecosystem as “surveillance capitalism” that worsens products (tracking in OSes, TVs, appliances).

Contextual advertising as an alternative

  • Several comments argue context-based ads (e.g. car ads on car pages) worked well for decades and respect privacy.
  • Google’s early success with search ads is cited as context/intent-based done right—though some dislike that these ads masquerade as “solutions”.
  • A worry: many modern sites have little real content/context and exist just to host ads; killing tracking could kill these sites, which many view as a net positive.

Effectiveness and economic debate

  • One side cites huge “economic activity” figures from ad platforms as proof personalization works.
  • Others counter that:
    • Industry self-studies aren’t credible.
    • Much spend is an arms race that mainly enriches platforms (broken-window analogy).
    • Targeted ads often underperform no-targeting; contextual could capture most value without tracking.
  • Advertisers are seen as locked-in: big platforms steadily remove manual controls and push auto-optimized, black-box campaigns with dubious ROI.

Details and impact of the EU ruling

  • The case targets the consent framework behind cookie popups and RTB, not ads per se.
  • Court found that identifiers (TC strings) combined with IP etc. constitute personal data and that past data collection via this system lacked valid consent, so data should be deleted.
  • The main fine (~250k€ for ~600 companies) is viewed as tiny “cost of doing business”, but the legal precedent is seen as important and fines are expected to escalate for repeat offences.
  • Some describe EU enforcement culture as: clarify law, give warnings, then hit hard; others say in practice it’s slow, easy to stall, and small actors can be hurt more than giants.

Cookie banners, “legitimate interest”, and dark patterns

  • Many blame industry groups for weaponizing GDPR via manipulative consent popups and broad “legitimate interest” claims (hundreds of vendors toggled by default).
  • Hope: this ruling will undermine those popups and the idea that you can “cookie-banner your way” into mass tracking.
  • Concern: sites increasingly force a choice between paying money or paying with data, which some say conflicts with GDPR’s ban on making personal data a condition of access.

Privacy philosophy, data as liability, and regulation

  • Strong current: data should be “radioactive” — collected minimally, treated as a liability, and deleted ASAP.
  • Others argue fully treating data this way is unrealistic and could disadvantage jurisdictions that restrict data while others don’t, especially for AI/LLMs.
  • GDPR is seen by some as well-designed (privacy-by-default, proportional fines, cooperative regulators); others highlight loopholes (state exemptions, slow cases, “legitimate interest” abuse).

Consequences for users, businesses, and EU tech

  • Some fear this means “ad-supported tech can’t grow in Europe”; many rebut that:
    • Ad-supported models are still legal; what’s banned is tracking without proper consent.
    • Contextual ads and non-ad business models remain viable.
  • Skepticism is high that major platforms will voluntarily delete historic data; expectation is more legal battles, slow incremental pressure, and possibly even more explicit but still manipulative consent flows.
  • Broad sentiment in the thread favors stricter limits on tracking, even if it kills some current business models; if a company “needs” pervasive tracking to exist, many argue it shouldn’t.
