There’s also a cost to transitioning to the new technology.
Normalizing arbitrary size removable media makes physical exfiltration much easier because no one is asking why you’re using an illegal technology in the government building.
Floppy disks are not able to identify themselves as a keyboard and release a payload of keystrokes on command, or hide entire soc computers complete with network adapters.
There is also the matter of retraining on an institutional scale, and if you think it’s as simple as “put this into the computer, not that” you’re woefully underinformed.
Just as an aside, it’s pretty fraught to compare a language transition caused by centuries of forced resettlement to switching the kind of computer thingy government employees use over the course of two years.
