The problem is not their personal account but the communities they manage, which are presumably also stuck on piefed and much more cumbersome to migrate and rebuild.

From another of PugJesus’ comments in this thread:

Yeah, as a user, it’s great to have options. If I was just an ordinary user, this probably wouldn’t even faze me. I’d hop over to Piefed.ca or something.

Unfortunately, I run several large comms who I managed to just about get to functioning without me…

… three times, so far, just before having to migrate and start the process all over again.
