No, they are not manufactured. The last manufacturer (Sony) ceased in 2011 or so. Some entrepreneur bought a ton of stock and is still selling it, there was an article around about this which I read recently but I can’t find it at the moment. A lot of customers who buy floppies are buying them for various government equipment, or shops with CNC machines programmed by floppy, etc. If you imagine that a CNC machine is designed to last decades and costs tens or hundreds of thousands of dollars, then buying floppy disks makes a lot of sense. If your government ministry requires floppy submissions because nobody bothered to update the rules then it makes less sense.
