And if you can't enforce your trademark, you don't have one, so why not just let it be free
Linus thinks its a good idea or he would have released the trademark. Its his trademark so he can do what he wants.
Just like Arduino team owns the copyrights to all the code and PCB layouts which they have licensed under CC.
Whether not they will use a lawyer to enforce those legal rights is, well, none of our business.
Anyways, Arduino team also doesn't have the fiscal capability to take someone to court if they break the CC license, either. Does that mean they should just release it all into the public domain and "get rid" of that responsibility?
