I agree with what you say. When we don't pay, then there isn't a huge incentive, but you know how it is. People on Slashdot keep yammering about what a great deal it is to open up the source [e.g. "Think of all the development costs that you'll save!!1!"], and how everybody should use it [e.g. "Think of all the purchase costs that you'll save!!1!"].
Like I said, I agree, but it's not appropriate to tell people that they should use it, or that open source is better, and then say that programmers don't care.
So, you say that you don't represent all programmers, which makes sense, but that wasn't the impression that I got. Then again, maybe I'm being too pedantic [or whatever]. Then again, this is Slashdot, and we can never know what is meant until it is spelled out.
I see that you have a 7 digit user number. Maybe you are new here; I don't know. I can say for sure, though, that many GPL advocates certainly did think that they were doing the world a favour by using open source software.
