Didn't know that.
I'm not a dev just a user.
I found the kernel quite stable and usable.
Maybe you can tell me what gpl is? Sorry again I'm just a user.

Excerpts from - http://www.gnu.org/copyleft/gpl.html
"When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things."
....
"For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights."
....
So Thor doesnt want to be GPL compliant and hence you cant have the source code of the kernel and hence no one else can develop on it to help the community.
