Counterpoint, what has Meta done to gain even the tiniest bit of the semblance of the doubt. If someone's punched you in the face every time you've knocked on their door, are you really going to knock on it a 15th time? You'd be a fool to expect that time to be any different.
Just like you'd be a fool to expect the overall impact of Meta having their fingers in the Fediverse to be anything other than harmful.
