Will it actually be cyclical? Twitter and Reddit tearing up their user base has caused the Fediverse to grow. I find it unlikely that - if Twitter and Reddit continue to go the way of Facebook, with the majority of the core user base leaving as enshitification worsens - they go somewhere other than Mastodon or Lemmy.

People can shout about how lemmy/Mastodon aren't user friendly - but with their growth they are massively improving and will continue to do so.
