Sometimes I wonder if Linus could go back and do it over, if he would license Linux under the BSD license instead of GPL. He's never seemed like a particular stickler for free software ideology, and has welcomed connections between Linux and industry. I don't know that it bothers him that much to see Linux used in proprietary software.
Not trying to start a flame war over licenses here, just speculating. And maybe this could be easily refuted by a link to one of his email rants, who knows.
