My question is if it's legal to distribute the pro version to others? It's open source but then I feel it unethical to share a software that is intended for financial support. I have been a pro user for a couple years and have always backed the software and when someone aksed me for a copy I old them they should buy and support the same as I do or use the free version like many. However, I got into a debate over it since it's under the GPL that it's distributable within means and compliance with the PLL licensing. I may be wrong but I thought the GPL granted this right and I find it very difficult myself to pay for something just to give it away free and the fact that many can just share and download it off the server themselves in a p2p environment.
