I have a Lenovo usb keyboard with a fn Key in place of the Ctrl key that has absolutely no purpose. It's for volume control like fn+F7 BUT... IT ALSO HAS DEDICATED BUTTONS FOR VOLUME CONTROL!!
After the nth time I accidentally switched fn and Ctrl I took a screwdriver and popped it out permanently (being USB it doesn't report fn status to the os and of course the BIOS doesn't allow FN remapping because it's not a laptop)
You don't need to go back in time to kill a Hitler wannabe, there are at least three in power
