@mcc The problem, IMO, lies in the differences of the nature of the enshittification.
Mastodon has issues with interfaces, details of exactly how federation does, etc etc. Things that at least theoretically can be fixed someday. Many may not be. Absolutely! But at least there's possibility.
In comparison, Bluesky is probably already doing bad things like gathering and selling user data and is going to eventually start participating in willful user manipulation just as its predecessors have done. It's inherent into its very design and nature that it must eventually do this. That's a different sort of problem and it's not going to be fixed because it is built in by design. The only questions are how long until it goes too far and how dangerous will it get. (Not looking good.)
