I should have guessed this would be a very unpopular opinion. Still think this is true.
Never used Instagram and barely ever FB. Never used twitter much anyway and a breed of Twitter and Meta seems like something I would never want anyway.
It seems people get some ego boost in saying: “We will not accept Threads in the fediverse”. But since they have not even attempted yet and have such a massive success, because they’ll probably dark pattern Instagram users into becoming threads users, they never need to consider using it anyway.
