I posted a medium-short summary elsewhere with a couple of links for folks looking for slightly more context.

I don't think the eris or defederation things are Huge News in themselves, but if it's true he doctored a screenshot to make the .art admin look bad, that's not a good look for a lead deve/flagship instance admin.

.art is an influential leader in community safety/moderation standards in the fediverse; their standards for federation are moderately high, and probably higher than folks on many lemmy instances would likely agree with. But it feels like the firefish guy has possibly a pattern of not doing his homework about things in general?

Obviously the big question is, did he actually doctor screenshots and if so, WTF, man.
