The is so rare. Such things can happen even with bank accounts (if you are a foreigner in many countries).
If you use your own Ubuntu/Debian or even RMS certified disro same can happen. An upgrade and you see only a xorg blinking cursor.
It can’t happen to my macbook.
This happened recently to my kid and it was a nightmare of a week trying to resolve it.
I’d rather tie my identity to an org with customer service.

This can be fixed yourself, whether that's hopping into a TTY or having to boot a live environment and chroot in. You aren't at the mercy of some major company's support people.
Even without fixing it you should be able to get at the files on the drive for use on another machine, or backing them up if you're gonna reinstall.
