Earlier quoted context omitted.
RMS wants user freedom, not developer freedom That is the point people always miss. RMS believes that end user of software / hardware should be in complete control, it was/is never about developers. BSD/MIT/etc lic may provide for more developer freedom, but often they are used to restrict user freedom as the code is folded/packaged into commercial projects with non-free licenses
It's a somewhat artificial distinction, since the user of a piece of software becomes a developer to modify it. And to preclude modifications which prevent him from effectively monetizing his labour is to infringe on his freedom. Prehaps it would not be if money (etc.) didnt exist. It's always the way, however, with idealists to prescribe policies that make people free in their utopia but cause chaos in our reality.
This sounds a lot like the people saying that adblocker software is infringing the freedom of people trying to monetize their websites (or maybe even "stealing" from them). And I think the same response applies: the fact that your business model isn't compatible with adblocker software, or with my choice of software license, isn't my problem.
Plus it seems extra presumptuous to claim some kind of inherent right to profit off derivative works of my software. You can only distribute derivative works of it at all because I've granted you a license. A royalty-free one at that! With the only condition being the copyleft condition: that you keep any derived works as open as the original. If you don't like that condition, we can negotiate a commercial license on whatever terms you want, with appropriate payment. Or you can write your own software...
