Torvalds is egotistical backstabber and a sellout
So what is his legacy... He took GNU operating system, made crappy kernel and named whole thing after himself. Then when original founder of GNU (Richard Stallman) complained and proposed to call the thing GNU/Linux, Torvalds ridiculed him. Linux is just a kernel, GNU is operating system with user-land parts like GNU Compiler Collection (GCC), GNU C Library (glibc), and GNU Network Object Model Environment (GNOME). All that is started by Richard Stallman in 1983, and you don't see anything called Stalmanix.
Also, Torvalds contribution to Linux kernel is negligible, and he takes all the credits. Real hackers like Alan Cox, Andrew Morton and others, deserve kernel to be named affecter them. Torvalds deserve nothing.
What else is Torvalds known for? He forced hackers to use proprietary BitKeeper. When he made a mess, he stared writing open source replacement for BitKeeper, and named it again, after himself: git. Now he gets credits for git, but in fact it was crap. He just started writing it, and people fixed his spaghetti code and made it what is today.
If 2006, he thrown FUD on GPLv3 and refused to even talk about switching Linux to it. That is very stupid and Microsoft is now exploiting his stupidity by shaking down big Linux users and extorting royalties for unnamed and probably non-existent patents. GPLv3 is designed to prohibit such extortion, to prohibit paying anything that looks like royalty on Free Software. Why Torvalds rejected GPLv3 ? Maybe because he got money from IBM, since they have a lot of patents and they want to reserve right to troll open source projects. They already lost right to sue since they are contributor, maybe they want to troll like Microsoft. But more likely that Torvalds was too stupid to make copyright assingment policy which would aggregate copyrights to some non-profit entity like FSF or SFLC. This way, all contributors must be tracked down. If he did due diligence, Linux kernel would be GPLv3 now, like GCC and rest of GNU is.
Then in 2009 he said that people who hate Microsoft are sick. Never mind that Microsoft is out to kill Linux. Never mind Microsoft is trying to tax Linux. (See Amazon, Samsung, Salesforce, HTC and Novell deals). We should love Microsoft because Torvalds said so. And he said so because he got money from them.
So I am not surprised that he now betrayed his country too. He already stabbed everyone in the back.
