YMMV. I’m sure a lot of people were shoving these things into backpacks, and this was post-2000, so the quality of disks for sale was poorer than it was in the 90s and 80s.
I’ve also (since then, for myself) repaired drives. The drives fail because they’re mechanical and have motors, and anything that moves or has a motor in it will need some kind of service. Servicing a floppy drive requires specialized equipment which is hard to find (or requires a lot of patience—it’s possible to repair a floppy drive with just a screwdriver, but it’s not fun; guess how I know?)
This is probably my "I'm getting old" moment. Good lord.
That they are still used in a critical infra item is a bit surprising. Getting new stock would be a major hassle.
People who grew up with or lived in the tech environment had access to lots of things.
