Magnetic degradation, wear from read/write heads, and environmental sensitivity mean disks have a natural expiration date and it's not long. And they are also easy to corrupt from all kinds of magnetic sources around us.
I get other stuff, even DOS like system. Safety critical software/hardware that was battle tested makes sense. Not floppy. Sometime it's just bureaucracy.

If you compare the thumb stick that came free from a convention then compare it to a floppy that came free with a magazine. And in the end neither matters because they’re both cheapest possible junk, not fair examples of the tech.
Similarly, the cheapest led bulbs (put in poorly ventilated fittings) have crappy lifetimes, but that’s not the techs fault, it’s because they weren’t engineered to last, they are cheap crap. Well designed leds placed sensibly are vastly better than bulbs, but that’s hidden by the cheap end of the market

In cold storage, a hdd should last longer than an ssd

Say, the Siemens PLCs I earn my living programming uses SD cards which range from 64kB to, uh, 128MB, methinks.
They still work after decades, so clearly, you can get long term reliable flash storage; just don't expect to be able to store your 4k holiday videos on them.
NOTAMs, on the other hand? Go ahead!

I wonder if quality control was bad. It seems like the disks that were good 30 years ago are still good.

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?)

On the other hand, 3.5" disks have higher magnetic coercivity, which makes them less susceptible to data loss from stray magnetic fields (e.g. nearby motors).

That they are still used in a critical infra item is a bit surprising. Getting new stock would be a major hassle.

I’ve bought some 15 year old floppies recently. They work. Had just to learn, that formatting them is required. In handling they are like SD-Cards.
Which is far better than the CDs, DVDs, Bluerays or records (you now…this big black discs with a needle).
And you don’t have to worry about network attackers. And we checksum everything from the network. For good reasons.

Without having details on the specific floppy disks in question there’s no way you can authoritatively say they are unreliable. They absolutely produced floppy disks that were far more reliable than the ones sourced from the cheapest vendor possible some of us used in school back in the day. Ignoring the fact I’m guessing the disks in question aren’t having to survive life in a students backpack.

One cost $100 another $1.
Then these tapes are typically write once read many.
They were designed to deal with floppy disk flaws consumers deal with.
Actually really cool to read about modern tape systems.

You really have no idea what you are talking about. It's normal for floppies, especially 3.5" to last decades just sitting on a shelf. I've got 5.25" floppies from 1984, and they boot just fine on my old apple //e.

The fact people have old working floppies doesn't change the fact that degradation happens.

First, the cover uses italic sans-serif “I” characters, not forward slashes. It’s pretty clear if you’re familiar with typography.
Second, the body of the document uses neither. It uses the standard upright I character.
As for the boot ROM, well, at the time, the character set was a fixed bitmap, stylized text wasn’t a thing on PCs yet, and slashes were as close as they could get.

because Apple did (and it was APPLE virgule virgule)
(the e when it appeared was lowercase)
They absolutely mog the cancerous garbage that is NAND flash memory in terms of data retention. The fact that you can pick an 1980s floppy from the junk room and read it is telling. Meanwhile your average TLC SSD will probably get wiped in 3 years if kept in the drawer, and a QLC will get wiped in 1 year.
Reliability wise floppies are also better: flash memory leaks electrons naturally and gets shredded by radiation events, with temperaure accelerating these processes. Meanwhile magnetic disks are not altered by any normal magnetic field you could produce at home.
