Stack Exchange as an organization might (somehow) be prohibited from releasing all of the background information that they have used for their decision making. But I am surprised that they haven't released any information, given the serious allegations made against them. And I haven't read anything corroborating Stack Exchange's "side" of the story, whereas a large number of people seem to be standing up for Monica.
I see three possibilities:
1. Monica telling the complete truth, there is a terrible misunderstanding, but SE doesn't want to lose face by backing down
2. Monica is lying
3. Monica is terribly confused
At this point, we all have to assume it's #1. If it's #2 or #3, SE really needs to come out and say something (beyond "we stand by our decision but our process needs updating") for the good of the communities. Stack Exchange is nothing without the community, since 100% of the content on SE was directly contributed by the community.
In one of the comments, by Monica it seems, she's not convinced of any wrong doing:
> "repeatedly violating our existing Code of Conduct": citation needed. "CM’s repeated requests to change": citation needed. – Monica Cellio
And later she clarifies that she doesn't know the specific thing that caused it:
>
@Randal'Thor let's start with them telling us exactly what part of the current CoC they think I "repeated violated". There's a lot of discussion in that email including of deeply personal identity-background stuff, so I want to know what the charge is before I decide if that response would help. They didn't even tell me what they think I did. – Monica Cellio
