Why in gawd's name would anyone mass produce such a device? This must be one of those fake news stories we've been hearing so much about.
I can't imagine any legitimate use for such a device, so I assume it would be made illegal as soon as the politicians can get off their duffs.
I'm sure certain companies and government agencies working with very sensitive information or critical infrastructure would find some value in it. You can disable USB in software or fill the ports with hot glue gun glue, but both can be undone/worked around. There may be other, better methods to secure the USB ports, but there are definitely some legitimate uses for such a device.
