"None of my clients ever redistributed their software, most likely because they considered it a competitive advantage." In some cases, it works. How large is your client base? 20? 50? Did your clients even read the license or know that they have the rights to redistribute it? If Photoshop were under the GNU, there would be a ton of free versions out there for anyone to download. Same thing with Windows or any other high-profile proprietary app. Both those companies would slowly start to lose money until they just couldn't make a profit any longer. It then comes down to who has the bigger marketing budget. "because I could reuse the code I did in other projects, something I wouldn't be able to do if I didn't license the code under the GPL in the first place." Are you talking about other people's code? I can reuse all of my code in any project, regardless of the license. "In other words, he fights for the users. ;-)" He sacrifices the freedoms of the developer for the users. Also making it impossible to make a living by just selling software. I personally don't ever use GNU code in any commercial projects. I prefer the BSD license because I can use code in any way and I'm not forced to give any of my future rights away as a developer. I also have released many libraries and apps under the BSD license.
