When I get nice service at a restaurant i leave more than the default 15% tips, to actually encourage good service. So when i find a really nice piece of software that actually saved me a lot of money (by increasing productivity and reducing licensing cost of other dev tools), i don't mind paying them a 70$ one time fee. Because in the end, they are not going to pay their employees with your respect. So, you have all the right not to pay them, you also have the right to leave shitty tips all the time and to not go voting. But i think i don't need to explain what will happen if we all act like that.
