If Lemmy.world doesn't defederate from Threads, Meta and all things Zuck within 24 hours, I will shut down my subs and leave.
I think the key is "not much margin" - they just aren't making enough profit and presumably don't want to put the price up.
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).
I think the point was that we don't need to use the sketchy service.
