How far you wanna go back to figure out what Linux would/wouldn't be without specific companies and individuals? You're taking "stealing credit for something" to a whole new level.
I’m a European who has contributed to the kernel (a single, pathetic patch but a patch nonetheless). That means at the very least it’s not 100% created by Linus
There are many, many things wrong with this statement, but let's repair it with past tense: "Linux was 100% created by an ethnically Swedish guy in Finland." The past tense from 30 years ago, the mid 1990s, because you've not been keeping up.
