Thank you for the insight. I've been on mbin for a while now and can say that I enjoy it. It does lack some features (like blocking domains), but it's quite pleasurable to use now. The upside is that it also can see mastodon and peertube and pixelfed. So far, I haven't read anything concerning about the devs nor any plans for limiting power-users.

Maybe they might be a good fit (and hopefully be the final switch, if you're still thinking about it).

Good luck! I hope you can still enjoy the fediverse.
