Even worse than that are people who contribute to chrome. Literally doing free work for the biggest tech monopoly there is so they can dominate one more medium and close the web. I was pretty hot on open source when I was younger but it really is a fools errand. Who is going to leverage that free software the most? Corporations. So instead of getting paid for that work, or plugging that work into something that would compete with them. Most of the people who contribute to linux though are people on loan from corporations like intel. That is why linux has adopted pc tech standards. Intel didn't feel comfortable giving resources to a guy who was rough around the edges, so they were going to stop lending him people. Which Linus needs those people to keep Linux compatible with new intel specs as they come out.
