"He is NOT arguing for proprietary software. He is however advocating for projects to own their copyright, so that they can build a revenue-generating plan around it."
The second sentence is equal to "He is advocating selling proprietary software." Owning copyright gives you only one kind of revenue-generating power. All other ways to generate revenue do not require copyright ownership. My statement is valid, he is arguing for proprietary software to help free software.
I am not saying he is wrong, but the fact that he, like you, tries to skirt around and obfuscate the rather simple way that free software people see things is really not going to help his cause.
