It seems to me a very reasonable explanation of why the post was removed. Your only response was "well then why am I banned from these communities?", and you were promptly unbanned with the only ask that you be civil.
I think you're describing the difference between criticism in the form of characterizing memes and criticism in the form of a formal accusation.
EDIT: also, out of curiosity, do you think if this was posted to .ml it would stay up?
If you scroll down in that post you find me providing a screenshot of targeted harassment against .ml in the exact same vein which stayed up for two months and was only removed after my comment was placed.
