Adidas = Adi Dassler
So what noun or adjective is "Adidas"?
I'm going to complain about being downvoted and I'm gonna grumpily say even HN isn't immune to anti-intellectualism...
The good ones in the list are good because they are not obviously a name of a person, the name of the thing makes sense independently to it being named after a person.
"Lake Mountain" could easily be named that because it is a mountain with a lake, so it is interesting that Lake Mountain is named after someone named Lake; Adidas and Debian are unexpected simply because they don't look like the name of a person, or anything else!
