Not sure about the other “mistakes” but this one is way too stupid to be evil :) Hanlon’s razor applies pretty well here.

Pretty sure no one thought “let’s add a lie to every commit and hopefully no one minds. Free Marketing yay!” at Microsoft.

IDK, I heard way stupider and less ethical ideas at work.

Even if I accepted the premise that this is too stupid to be evil, that doesn't change the fact that this would be extremely easy to test for. The fact that they considered it important enough to get this feature implemented without proper testing says plenty about their incentives.

They might not have intentionally done this (although it's honestly not clear), but they definitely didn't care enough to prevent it because it wouldn't have been hard at all. That's my point here; which bugs slip through and which don't implicitly conveys what their priorities are. I don't think it's particularly hard to infer what story this bug tells.
