title: What happens to those who break open source license?
body: <p>What happens if you break an open source license and include a code released under GPL in a closed source project?</p>
  
  <p>Can you go to jail? Who will sue you? For what? "Not respecting the will" of those who created the free source code? Is there any support in the jurisdiction (of any state) that would put any punishment to those who do not respect software freedom?</p>
  
  <p>Inspired by a question I have just seen on SO: <a href="https://stackoverflow.com/questions/935612/is-it-allowed-to-use-ideas-from-open-source-in-closed-source-softwar">Is it allowed to use ideas from open source in closed source</a>, not being able to find any answer to this question. </p>
