There are some factual errors in that graphic.
(1) Gab didn't leave the Fediverse because leftish instances blocked them, but because the instances that didn't block them mocked and harassed them.
(2) Truth Social never attempted to federate. They removed that part of the Mastodon source right up front. (Source: Alex G, who was their lead dev for a while.)

The other thing to consider is that the Fediverse is losing the user-recruitment contest to Bluesky and a big factor in that is that Fediblock means no one can be sure they'll be able to communicate with their desired contacts on another instance. (Nostr trumpets Fediblock "censorship" as a reason they're supposedly a better place to be.)

In my opinion, relying on things like Fediblock has greatly delayed necessary things like automated spam-blocking and some sort of individual filters that are user-subscribable. (This one is a feature that Bluesky has, but in my time as a user there, I've never yet come across another filter provider.) Other than illegal content, admins should be very careful about blocking, because they're in a position of power relative to their users. I'm 100% not saying they shouldn't block anything that isn't illegal, but they should think about how doing so from their position of power affects their users before doing so.
