Now, how would you make money on free, as in libre, software? How would you make a free, single-player RPG and still stay in business? All you can under GPL is take payment for distribution, as long as nobody else starts to distribute it for free. This means giving your hard work for free, as in gratis, not business.Ask RedHat, or any of the increasingly large number of companies that *do* make money on free, as in libre, software. Basically, you make your customers pay for specific developments and customizations. Once the software is released you still get paid for tech support and maintenance.
And then, of course, there are the library developers that release their work as GPL, but sell commercial licenses to those who want to use it without GPL restrictions. Of course, one could argue they don't make money on the free (as in both) software, but on the non-free version of it (which may have identical code).
