Keith Casey has an excellent discussion on the problems posed by GPL3. Clearly Stallman has decided it is all or nothing and may very well get nothing.
I had the privilege of seeing Stallman speak. He is emphatic that living in freedom means using free software. Having looked at the controversy over the voting machines and assorted spyware controversies, I am not sure Stallman is wrong.
On the other hand, companies want to be paid for their work. How can you provide for that in the absence of copyright?
One thing I do know, software is too important to leave to the techies and this is a discussion we all need to follow.
