"On the other hand, copyright infringement carries statutory
damages (a set amount that you get without having to prove monetary
damages) and also allows you to recover attorney fees. And, most
importantly for licenses such as the GPL, it means that your rights
to use the copyrighted work at all disappear. That's really
important with GPL and GPL licenses, which are in a very real sense
a social contract that says "I will let you use this for free, so
long as you give back to the community for the greater good."
