I'm not upset.
I can prove it to a remarkable degree with the welcome email 3 days after this model was launched.
I didn't lose backup to account. I'd already migrated to the latest M1 MacBook, and my account is fine.
There's appears to me to be no backup to the firmware lock, there is a backup to FileVault, I have file vault.
I get it and am not complaining. But person above me said it wasn't a real problem.
My point is, it can be a $4500 problem for a legitimate purchaser.
