Companies can be named after random nonsense, ‘pink catfish’ could easily be the world’s #1 supplier of firearms and nobody would find it strange.
Caterpillar, Apple, Kellogg, etc really don’t have anything to do with the underlying product but neither do people’s names.
Caterpillar does have a lot to do with the product. It crawls on a track and a photographer thought the track looked like a caterpillar .
And they went out of their way to sue anyone that dare to use the cat word in the name or anything resembling an apple in the logo.
They didn't have "open" or "free" as prefix.
