If ya want to not be plugged into the internet, or use new external media, ya can probably run it safely forever.

Bad eh security advice: use an alternative ssh port. Lots of actors try port 22 and other common alternatives. Much fewer will do a full port scan looking for an ssh server then try brute forcing.

I’m perfectly fine with competition. This is the world. I’d buy a cheap Chinese car that passed regulations for driving in my country.

Trying to tariff instead of competing is just delaying the inevitable.
