The fundamental problem is the business model where money is parasitised from people's attention. You want change? Make these companies responsible for the negative externalities they impose on society, just like companies that pollute the commons are held responsible.
We don't need another Tiktok ban; we need industry wide regulation. Shortsighted focus on single companies is simply a distraction from this fact, which only benefits these companies and allows most of them to continue as before.
Which can lead to websites like Reddit making unpopular changes to try to match Facebook's market cap (I think I've read they were specifically trying to do that)
If you create fake metrics everyone else will copy you in a race to the bottom
No other CEO begins the company with "If you need info on people at Harvard, just ask, they trust me, dumb fucks"
Have you not looked at Musk recently? Or is supporting AfD (the German far-right party) and adopting the persona of "kekius maximus" (a right wing meme) somehow less scummy than whatever it is Zuckerberg is doing?
Mind you, Zuck pulls some fucked up crap -and some of it may well be worse. But my point remains ...he's not alone. All of the Social Media platforms are corrupt and toxic and in many cases...Musk, Spez..their owners are as well.
(Instagram as you probably know is also owned by Facebook and people are similarly tired of the constant spam)
