But how about, say, Lemmy, or other self hosted places

Well... how many Lemmy instances are hosted in the EU, Canada, USA, Australia, UK, ...? They can be threatened under the full power of the state, unless they req ID checks.

OK, you may say, just use one in Tuvalu! But someone below mentioned it. Govs will not think, gosh darn it! I guess we got foiled by those rascally nerds! Pack it up guys, we lost! No, they will double down. They will create national firewalls. VPN bans. Already the UK, and Utah in the USA are pushing for VPN bans. They will make examples of people, to deter the rest.

It's very hard to solve political probs with technical methods.
