Would you search up "reddit like alternatives" if you hadn't been banned? And if someone came on Reddit a few days before you got banned and said to you "hey, this is the Fediverse, come join us", would you join, or would you say "I have no reason to leave Reddit or to use any other Reddit-like platform"?
I also don't it's a "disenchantment" problem. I believe it's more of a "refusing to change because it takes effort" problem
