The problem lies in with the fact that they're the largest instace on lemmy by a significant margin so they control the playing field. This is like trying to wait for reddit to kill itself. It's not going to because people start relying on it and getting too used to it and don't want to bother with anything else. Combine that with admins that are actively harming the fediverse by driving new people away when their instance is the first thing they see? They need to be held over a barrel until Kaplan and Serinus are gone. As for your usage case:
or speech which would drive away marginalized people from our instance to avoid seeing it.
The official LW Admin account is officially considering sanctioning and defederation from Dbzer0 based off of a purely slanderous case made by Kaplanwas that the admins of this instance didn't take it seriously enough based off of their feelings.

Kaplan has no evidentiary basis for a consideration for this defederation and even admitted as much. If we roll over and accept that then what is even the point? Just accept that Lemmy.world is going to continue throwing hissyfits and the rest of the Fediverse just has to accept it? I want to see something done for outrageous threats made against not just the instance but all 20 thousand users that Kaplan is ready to handwave away based off of their feelings.
To use Kaplans own words here, it is not my intention to control who can or can't be on admin teams on another instance but I do expect other instances to understand that an individual admin's actions reflect their instance as a whole. Something Ruud seems to not care about and something that Kaplan belives does not apply to themself. Overall, the primary response by the LW Admin team has been to frame AN and Dbzer0 as either a small instance that "only has 165 users" or a "vocal minority with an agenda". For 20,000 users.
There is a significant difference in the tolerance of hypocrisy on our platforms.
