It's not for you to exploit to make a buck
Of course it is... That’s what Google does, that’s what all companies who are large enough to know how to work around the GPL do. Every company who uses it on their own servers without telling you, or even compiles and distributes it hoping that no one notices, does. And when they do, they sometimes contribute resources back to the project, which helps it to thrive.The GPL is very ideological, and there’s nothing wrong with that but you can see the cost of that right here: where someone pointing out there is a hidden cost is shamed for doing so. Given the chance of contributing code or community to two similar projects, I prefer the one that’s more about building than it is about contracts.
