A misleading headline. Not too different from the last round of headlines that there are card carrying fascists in the fediverse. Both are true and they are blocked by all well run servers.

This is like the web and just like we don't say that HTTP has a X problem it doesn't make sense to say that open source software run by thousands of people across the world under different laws has any specific purpose or problem.

Improvements can be made to the software but bad admins can just rip that code out. Still I bet good instances will make changes.
