The EU moves to kill infinite scrolling

📝 Discussion Summary (Click to expand)

Three prevailing themes

# Theme Key quotes
1 Cookie‑banner over‑reach under GDPR “Having worked at multiple companies … we still need a cookie banner.”rpdillon
“You don’t have to have a cookie popup if you don’t do stupid stuff. Don’t use anything other than strictly necessary cookies and you are good to go.”mcny
“GDPR consent dialogs are only required if you share data, i.e. spy on the user.”dathinab
2 EU’s attempt to curb addictive design (infinite scrolling) “The do‑not‑track header was good enough in this German case.”jeroenhd
“They are not creating laws against infinite scrolling, but are ruling against addictive design and pointing to infinite scrolling as an example of it.”jjcm
“The EU had a real problem with addictive designs and social media the time to move against it was of course 10+ years ago.”spwa4
3 Regulation vs freedom, dark patterns, and addiction debate “Why would anyone care about something like this to the degree they feel like expressing the opinion publicly let alone in a political regulatory body is beyond me.”ben_w
“This isn’t about addiction, it’s about censorship.”ARandomerDude
“Because it is a dangerous addiction with recognised adverse effects on human health.”Rygian

These three threads—legal‑compliance anxiety, EU‑driven design regulation, and the broader clash between regulation, freedom, and dark‑pattern concerns—dominate the discussion.
