When I was made aware of Urbit, there was someone prominent related person, a friend project of Nock or something, who had developed another competitive functional OS of his own, some kind or other, if memory serves, who had also parted ways with the community over some controversy which nobody wanted to talk about, and at the same time nobody else on the outside of it evidently wanted to ask about. I don't want to mis-attribute anything, because I am light on details, I won't try to recall his name, or what it was over, being from the outside myself, but I distinctly remember some part of the controversy being about someone or other "refusing to put up [some kind or other] sign in their window," (I inferred that it was metaphorically speaking.) It was a metaphor for something I didn't know, but I distinctly remember coming away with the feeling that I also didn't want to end up displaying that sign in my own window. To restate what I'm dancing around, in no uncertain terms, it seems to me that you're asking for a sign in the window. "No Moldbugs Allowed."
