I've been part of a few projects where we blackout EU locals. Just not worth the risk.
All they ever did was installing an advertising channel into our inborn desire for socializing. And the pathological interaction of social media and individual and group psychology have been discussed at length elsewhere.
Countries shouldn't put up with such BS. US is all about the free market until Tiktok showed up, which shares data with the government like how meta shares data with the NSA.
That would of course lead to the rise of an EU-centric facebook-equivalent within a few heartbeats, so it's pretty likely Facebook will back down.
Might as well go after that before the problem becomes even worse than it already is. It has been known that like Meta, TikTok abuses the privacy of its own users for the benefit of its so-called and worshipped 'recommendation algorithm'.
Next comes google.
TikTok is getting scrutinised and having state-level bans in the US and is already getting their warnings and being in the cross-hairs of the regulators in the EU. [0]
Next, TikTok will face hundreds of millions of dollars worth of fines and if repeated it will be in the billions.

If its even legal, because Schrems isn't going to back down any time soon.
