This is not my personal opinion, I know Gen Z men who voted for Harris. But the voter demographics really speak for themselves, and maybe now people will look at the radicalization of young men as a serious (but solvable) issue.
We both know the government is never going to split them up
The American government isn’t going to. But, I do hold out hope for the EU. The EU already doesn’t like the US tech giants, and they’re much more driven by lobbying by European-based businesses, almost none of them on good terms with the US tech giants.
We’ve already seen what effect the GDPR had on the web, and it affects Americans even if the law doesn’t apply in the US. We’ve seen how Apple has had to design all its devices to use USB-C because of new EU rules. I think it’s pretty reasonable to expect that the EU might require Mastodon-type rules for social networks, that you can leave to an instance that communicates with your old one, and that your followers and followees change when you move. Facebook would hate it, but Google (whose social network efforts all failed) wouldn’t really be affected, so they might push for it just to spite Facebook. Some of the other big American tech companies might actually like it. Like, Netflix might like to be able to graft a social network onto their video watching platform so that people could watch and talk about videos together.
With the Biden administration going out and Trump going in, I think the FTC is going to go back to being a corporate cheerleader, but I still have some hope for the EU.
