The Fediverse did take off. Then large numbers of influential people got banned by randos and realized how much better and reliable (non-profit or not) corporate censors are.
I understand your pedantic point but let me give a realistic reply. If your account, or the account of somebody you like corresponding with, happens to be on an instance that falls into disfavour (not uncommon in my time there) then server bans come out and conversations become broken, even between parties who had no knowledge of the overarching drama. Good luck even understanding it if you aren’t a techie.
Every server admin can ban your account. You can’t move a banned account. You lose everything. I was banned from mastodon.social because I dare to criticize the socialist regime
of the former GDR on Germany‘s Independence Day.
Well, some of the non-centralized social media is quite left-wing. If someone favours the SED or other parts of the ex-GDR regime (like FDGB etc) then it's IMHO already bordering on left extremisms. After all these guys enslaved a hughe population to make people do their biddings. If that is not extreme, I can't say.
That said, if you insisted that some "Germany's Independence Day" existed, then it's perhaps that what got you banned. Germany was never really a colony. Not of UK, not of Spain or Portugal, or not in newer times of Russia. Many countries that were a colony of them, or just annexxed, have an independence day. Germany doesn't --- the last time it was partially colonized, in roman times, there was no Germany.
