Ads and spam is what's ruining everyone's experience. If we would pay for services rendered then there is no need for tracking. If we could effectively prosecute and/or block spammers then there would be no need for anti-spam algorithms (from email to services like twitter and discord, iirc yesterday there was a thread about automatic bans based on secret algos with no recourse).
Government regulation is an attempt to make people aware this tracking exists: every time you see a wall, that means the site requires a level of tracking for which there exists no legal basis other than consent, thus it has to ask you if you're okay with that (like any ethical site should do anyhow).
Automated decision making is also part of GDPR but unfortunately is very very weakly implemented. Basically, companies just have to tell you it exists (if and only if it has a significant impact on your life), and then your only recourse is to request a human in the loop, and they will just press the same button as the AI did and you have no idea if they even looked at your case because the decision making doesn't have to be transparent. And that's only for important life things, none of this even applies to being banned from google account unless you sue them and get the judge to agree this has a major impact on your life.
You don’t see the problem with this?
