It's a bit tedious to have to explain that service providers have certain responsibilities and obligations too. Corporate culture has given bigtech a blank cheque to behave the way they want. That aside, based on the way you framed your reply, let me assure you that I don't trust them with even my projects, much less the CI system or their runner. And time and again, they vindicate that decision. I have posted the full argument as a reply to your sibling comment.
