Lemmy? The good news is, due to it being decentralised, federated, and free and open source, it's resistant to takeover and enshittification, as there is no one central authority that can dictate things for everyone.
If the Lemmy devs make some bad decisions, instance owners can choose not to update. Forks can be made to remove bad things and add more good things, and bad instances full of bad people can just be blocked from interacting with everyone else.
