yes

They hold "system binaries" meant for root user. It's not a hard distinction but many if not most Linux fundamentals have their roots in very early computing, mainframes, Bell and Xerox, and this good idea has been carried into the here&now. Not sure about the provenance of this one, but it makes sense. isn't /mnt /media different between distros? These aren't hard and fast rules - some distros choose to keep files elsewhere from the "standard".

/bin and /usr/bin, one is typically a symbolic link to another - they used to be stored on disks of different size, cost, and speed.

That is inherently a gift then, donation? No different that giving it away and morally lesser to giving to the poor. Breaks one of the rules.

It could but the concern weird be rattle if you have any. I what wouldn’t fall do the whole “keyboard specific dampening foam”, I use packing foam on my keyboard between the case and PCB and it’s totally fine. But the PCB is also screwed into metal standoffs in a wooden case, and I have no plate. Surprisingly I don’t have an issue with switch movement. And the seller stopped selling plates while they unloaded stock of PCBs. I’ve been too lazy to reverse engineer the plate design, which the seller also for some reason did not want to release (even though they had released other plate designs). Really dumb. But keyboard works so whatever :)

You could add rubber feet, sub-pcb foam liner, lube the switches, o-rings work too but feel awful. Also having a neoprene keyboard/mousepad helps too. I’d recommend positively affixing the pcb+plate to the case so it doesn’t rattle either.
