Pretty much, but its a tad complex.

Microsoft hosts for example in Ireland (part of the EU), but is an American company.

A subreddit has its own moderators and rules, but has to also adhere the global Reddit policy.

FOSS is developed by people all over the world.

One solution is to lay low and be low profile. For example, an invite-only system, or E2EE. Another is to host in a more liberal country. But if the website is in Russian, it is assumed that its being served for Russians (people in Russia).
