Regardless of the criticism specifics, a visible mod/admin is a bad mod/admin. True leadership follows; the steering, imperceptible. The job is that of a janitor. People can appreciate a janitor. When a janitor tries to play president, hate follows.
I haven't seen the specifics in this instance. I saw someone posting partial private messages in screen shots months ago without full context and making drama. I have not seen inexcusable behavior from .ml or a reason I feel motivated to stop posting there.
That's just the more prominent example, what others would you like?
How about the .ml admin who told a user to kill themselves and is still an admin? Or how about the general toxicity of their users towards Lemmy newcomers? Or the BlueMaGA crap? Or how about likening Harris to fascism when there was a literal textbook fascist, Trump, on the ticket
