Let's hope people will move on from OnlyFans. Truth Social was a joke, but I think Twitter will still be as central as Facebook and Instagram and perhaps we never will see a platform that harbors that many users.
TikTok is another beast. It is used by almost everyone but I never met one that had meaningful interactions on it. It is the laziest form of entertainment. Successful, but lazy.
Most of the Twitter Blue subscribers were those that bought into the freedom of speech aspect of Twitter 2.0.
They will likely stay where they are but everyone else will slowly but surely move.
