Fwiw, you catch more flies with honey than with vinegar.
I for one am extremely happy to see PieFed flourish, and one of my chief reasons to move to it 8 months ago was specifically to block lemmy.ml.
That said, I have no desire to “cancel” anyone at all - and the Lemmy devs are worthy of respect for their accomplishments, even as they also deserve some criticisms for the way that they run their instance.
I love how the future allows PieFed and Lemmy - and Mbin, nodebb, flarum, friendica, mastodon, pixelfed, etc. - to exist altogether in the Fediverse, without needing any of the others to die out. I even maintain accounts on both PieFed and Lemmy instances, as each currently offers features that the other lacks.
(also, if some of the lemmy instances were to be cancelled, then all of their users would come over to here… think about that for a moment, is that a desirable outcome to you? :-P)
PieFed, Kbin died but lives on in its fork Mbin, Sublinks didn’t pan out but was started (the PHP code is FOSS), nodeBB, and flarum.
You may also occasionally see posts from Friendica or Mastodon that also use the ActivityPub protocol, though the barriers to sharing those with the Threadiverse are somewhat high.
