I was just reading about pirate radio stations. One pretty bitter post by a busted pirate radio operator went like “while a large number of police officers were busy chasing us through the forest, a guy got stabbed to death in the downtown. I think the raid on us was a gross mistake of police resource allocation.”
This is like that, but even more petty.
/mnt is meant for volumes that you manually mount temporarily. This used to be basically the only way to use removable media back in the day.
/media came to be when the automatic mounting of removable media became a fashionable thing.
And it’s kind of the same to this day. /media is understood to be managed by automounters and /mnt is what you’re supposed to mess with as a user.
