I have stopped contributing to the Stack Exchange sites in disgust over the treatment of Monica Cellio (and, by extension, the entire user community) by Stack Exchange, Inc.
And yes, "disgusting" also describes the non-apology SE posted on December 23. 2019, which does nothing to repair SE's relation with its user community.
It was nice being here while it lasted, and I wish I could come back. But I really can't see myself contributing my writing to a company that acts like this towards its users and volunteers. At some time when I get the time, I'll probably put up a collection of my Math.SE answers elsewhere.
