Shills, activists, trolls, state actors, and advertisers follow the eyeballs. They don’t give a crap if it is on the fediverse or some other platform.
If the fediverse capabilities can’t evolve to provide controls, then it’s doomed to failure. It’s already bad enough that bot accounts will create a new community then spam the crap out of it to appear on the “hot” view. Expect this to be turbocharged as the US enters another election cycle.
