Maybe here's a miscommunication. I meant no price, no need to trade my copyright, and maybe you're meaning freedom to access source code - strict GPL meaning.
Also I haven't argue payment itself is bad. Go back and read carefully my reply. Fair trade is good, and I would gladly pay for good product.
My original intention was using HTML as a GUI toolkit layer, and I realized that was wrong idea with PNaCL. It's exactly opposite concept. It's my mistake. I'm sorry for that.
Wow. now I see PNaCL is really completely useless except for Google's API dominance.
Not all of them have GPL licenses, plus it is only fair to pay people for their work.
