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.
I post criticisms of Russia and China quite frequently, the critical part of "critical support" doesn't mean critical like "it's a critical attack!".
With Russia though, literally the only context where the guys who destroyed the USSR and caused the greatest non-war-related drop in human life expectancy, increase in suicide, increase in child mortality, increase in alcoholism, etc in the 20th century are a better alternative is in the context of opposing western hegemony.
Like you're not going to see a ml say anything nice about Russia, only that it's less evil than the west.
