I don’t think people are switching to BlueSky to enter back into an echo chamber. In my experience they are doing it to avoid aggressive ****e adverts, the very weird algorithm for post selection that’s now used and the litany of one-subject bots. It probably won’t last as it is for long, but it’s good while it lasts.
Twitter is a cesspit like you say
And im not even talking about poltical views or such
Its absolutely full of bots etc
