Banning dragnet spying and/or making retaining data about people very risky, has some chance of killing algorithm-feed social media (by drying up ad dollars) and would be a good thing to do anyway.
Making companies liable not for content they host or deliver/show to an explicit recipient or set of recipients, but for content they both host and actively elect to promote, would kill the algorithm feed, suggested videos, et c, but not ordinary Internet hosting services or messaging platforms (or even traditional forums!).
Neither is impossible, and either would probably be good to do anyway.
If the core problem is companies shoving shit at you based on what drives "engagement" and with little regard for anything else, those are policies to look at.
