The dev does plan to open source it I believe.

Yes, it does.

Takahē are going to try implementing it too, once Bluesky are ready to federate.

I think they just get marked as deleted, and what is supposed to happen is that the deleted comment gets picked up through federation and the destination server should delete their local copy. Sounds like that isn’t happening between Lemmy and Mastodon.

There’s some I haven’t used, but Kbin will do Mastodon-style microblogging and Lemmy-style threads, so that’s the best of both worlds. I don’t think the private messaging function works on it yet though.

I think the point was that we don’t need to use the sketchy service.

Companies can host Mastodon (or Lemmy or whatever) on their own domain. That way they have control over the instance and it implicitly verifies their account as official. Raspberry Pi already do this (raspberrypi.social).

Friendica, apparently. I’ve never used it.
