Ask HN: Does GitHub Copilot now leave unsolicited PR review comments?

I must have missed the memo but is it true that GitHub Copilot now leaves PR review comments even though nobody enabled it?

I saw it happen in some projects I follow. I don't think the project authors enabled Copilot reviews. Trying to make sense of what's going on.

I guess I'm trying to understand this - If I create a PR on my repo, is it possible that Copilot will come to my PR uninvited and leave unsolicited PR comments? If that's correct, is there a way to disable it?

(Please don't treat this question as ragebait. It's a genuine question and I'd like genuine answers please.)
