I had the displeasure to operate a sort of industrial/automotive rack computer running very simple Simulink data logging that booted only from a floppy, and I think it was bought around 2008. For a greenfield project.

Probably cost like hell and was decade or two behind in technology, but I didn't buy it and definitely wouldn't have. Salespeople get people to do stupid stuff.

I'd guess these are used a lot in industrial settings where the code and task is actually very simple. Would run no problem with a $1 microcontroller and a hundred lines of C and with a lot less hassle. Likely vendors have gotten a reputation and keep on selling them with FUD.
