I think in the later dying days of the floppy disk, the manufacturers made them with really poor quality. It used to be in earlier years, say the 8-bit years when floppy disks were still floppy, that the disks could keep your data for years if you treated them like vinyl records and never touched the magnetic surface.
In the late years, I’ve seen floppy disks that failed almost immediately.
I haven’t seen any yet either, but I’ve been religiously updating my ublock Origin lists and keeping Revanced up to date.
