They absolutely have. They force upgrade computers to Windows 11, which then won't boot, because the system doesn't actually support it. I guess they also have a smoother way to achieve that. They are also cases where an update broke the booting process, so the bitlocker key was lost. Everything is encrypted with it by default, and the only copy sits on a MS server connected with you MS account. Guess what happens when they say sorry, we can't just give you that key...
