This is the real shit right here. The problem is that social media companies' data show that negativity and hate keep people on their website for longer, which means that they view more advertisement compared to positivity.
It is human nature to engage with disagreeable topics moreso than agreeable topics, and social media companies are exploiting that for profit.
We need to regulate algorithms and force them to be open source, so that anybody can audit them. They will try to hide behind "AI" and "trade secret" excuses, but lawmakers have to see above that bullshit.
Unfortunately, US lawmakers are both stupid and corrupt, so it's unlikely that we'll see proper change, and more likely that we'll see shit like "banning all social media from foreign adversaries" when the US-based social media companies are largely the cause of all these problems. I'm sure the US intelligence agencies don't want them to change either, since those companies provide large swaths of personal data to them.
