I was pondering a few open source licence issues over the past few days (like the Goldman Sachs case - http://cryptome.org/2014/04/goldman-sachs-code-thief.htm) and I was wondering, does anyone in the HN community have examples or links to places which show violations of GPL licences actually being enforced? I.e a commercial company takes the code, adds, repackages or sells it commercially in some way - without actually making it available publically for free? Has there been cases where an open source project was compensated for the abuse of licence? I know this site has stuff http://gpl-violations.org but it's got very out of date. I love the open source philosophy but it would bug the hell out of me if something I was doing was abused in this way - without adding to the community or compensation etc.
