regarding the "losing people to Bluesky" thing, I think Soatok Dreamseeker (npub1wfp…w2m9) nailed it in his blogpost:

My personal broader take is: fedi simply is not ready for the mass influx of new people right now. And we know what the issues are: moderation (especially of racism), on-boarding, etc. These issues are solvable, and they need to be solved.
And that's fine, as long as we do learn and improve so that we are ready for the next waves.
This is a marathon, not a sprint.
