I still don't get how, IF the application was GPL'ed, Matan's actions violate the GPL. The GPL insists that all software licensed under it, and all software developed from or based on the initial GPL'ed code, must be distributed with the same license, which gives an irrevocable right to obtain the source code, and modify and freely distribute the software, with or without modification, so long as you give the same rights and opportunity-to-acquire-source-code to everyone you distribute it to.

Which ultimately means that it's a question of how Matan acquired the source code. Honestly, the way I understand it, unless Matan acquired the code/binary (I don't know what he was distributing - the link was down by the time I saw this thread) in a way that was obviously illegal, the GPL's protections stand - or at least, it would be hard to challenge in court.

IF, of course, the StellariuMobile is a GPL'ed app - it could very well have had that left in accidentally, or something.
