Is the assumption that non "tech industry" communities (e.g: voat, parler, ovaries, gab, truth, lemmy, mastodon, 4chan, 8chan, etc) are less likely to be a problem or to negatively impact teens than the mainstream "big tech" ones (e.g: facebook, twitter, youtube, tiktok, reddit, etc)?

Because Fedgov stopped any real anti-trust regulation over a century ago and have shown they have no will nor ability to change that since.

It's not going to happen, at least not in the land of crony capitalism.

I agree. It’s just there has not been a pro-EU vote in any form or capacity by any EU population. So the stopped doing referendums but the EU grew only even more unpopular- and lately with VDL and KK, its as if its a cruel joke we all expect for it to end soon.
