he is just wrong! (Score 1)

Paul Murphy is just wrong. His argument:

He'd like to get into the Linux market, but to do that he might have to use some GPL'code

Nobody have to use GPL Code!
He can just write his program for GNU/Linux like he writes his program for Windows or MacOS! The difference is that he has the option to be part of our community and build upon our GPL code. But that's just another option, an option that doesn't exist in the proprietary software world at all!
At the end just everybody have this additional option but nobody force someone to use this option!
Take this option and be part of our community or don't take the option, don't look at our code, don't use it and just write your own code like you would do it on windows, macos or every other os. There is no problem at all!
