It would be interesting to read Torvalds' response to this article as it paints a very one-sided picture.
If we presume the article is at least in the right direction, from what I know about some devs, I presume he sees Linux as "his" baby that he just happens to be sharing with the world. If you like it, great. If you don't, idc. This seems to fit his character of harsh criticism of bad code. On the bright side, it has always meant that Linux has had a critical eye examining it, ensuring that it works. On the flip side, some feelings are hurt. But that's ok. You can't always appease people's feelings if you want something done right.
In a way, Torvalds is more true to liberty than Stallman: Do what you want with the code. Stallman is more "Let's all share freely." They form contrasting camps to the FOSS community, which is one of the many reasons the community can't just all agree.
