The beauty of the Fediverse is that many tasks like this can be done by the client, as opposed to the actual base software.
For instance, Lemmy can’t actually block instances or “subs” (or whatever the equivalent is) on an individual level, but Voyager can.
On another point, as much as I hate hearing about Musk and Twitter, they are both very powerful, and both have an impact on the world. Especially if Twitter were to become an “everything app” (AKA Superapp)(which it hopefully won’t).
