License compatibility is a legal framework that allows for pieces of software with different software licenses to be distributed together. The need for such a framework arises because the different licenses can contain contradictory requirements, rendering it impossible to legally combine source code from separately-licensed software in order to create and publish a new program.
McHardy's strategy was to approach a commercial entity with minor GPL violations — such as attribution deficiencies, lack or inadequacy of a written offer for source code, or an EULA conflicting with the GPL license — for the sole purpose of obtaining an undertaking to cease and desist from further infringing activity and including a clause ...
