Everything is political. But that isn’t what the poster or other users of this particular lament mean.

In this case, “Politics” means “politics other than the ones that I’ve decided are normal and not worth questioning”.

This is a particularly fun meme here; the whole point of moving to Fedi is to get away from the current ownership of the public forum, that ownership itself a matter of politics ( who is allowed to own things, who is allowed to enforce rules, etc ).
