If people want to create and promote their own utopian models that's their business. Personally I'd want nothing to do with that, and it definitely should not be called open source, just like any restrictive license.
On another note, a transaction is a meeting of the minds. When most people release open source software they want nothing in return and are owed nothing. That's how I feel about it. People who think they are owed something are like beggars who do miming or some such in the street and call it work. Nobody asked for it, some find it interesting and you might be able to guilt someone into paying but they didn't hire you and don't owe you anything. You can just not do it, it's only a job if you're explicitly hired.
sure, but an entrepreneurial effort is one that is done without requirement of reward but expectation of being able to derive reward.
It seems a lot of what is called open source is done under an entrepreneurial model, the same as much writing, mimes on the street, or a million other things.
