Yes I did. Of course there was a screw-up. Maybe people can bring back backups, maybe not. This is nothing new and the devil is in the details. It could just as likely've been a flood, fire, short-circuit and everything else.
Nevertheless, data inevitably gets erased. It's part of the data management lifecycle. If data is non-trivial to backup or obvious to find, it must not be very valuable to those who own the data. Think about it.
Not deleting data, you might even become criminally liable, according to privacy laws like GDPR.
So while this stuff isn't as clear-cut, stable and easy as it should be (we agree there), people must keep their data with them, if the data is valuable to them.
I don't see any way forward laying blame on others for the rest of one's life. That's no way to live.
This is why one implements data and IT governance.
Ownership is with the user.
