 Wrong. Because Bob violated the GPL, right? 
 
 By not putting a licence file or giving the source. You put a license
 and provide the source. No more violation.
  Remember? I'm pretty sure
 I'm telling you something you already knew here, but he DIDN'T
 release
 the source code for the preview release. He SHOULD have but he
 DIDN'T,
 so you never got the GPL'd source with the preview mods in it. This
 put him in violation of jMusic's license but it did NOT magically
 grant you copyright, copyleft or copyanything to the code he should
 have released, but didn't. 
 Wrong. There is nothing in the GPL that says you cannot add the
 license
 before you distribute. Think about it. You get some GPL code and
 change the
 license to add in another copyright in addition to the original, as
 per GPL
 rules. Where does this text that you are adding in come from? Where
 does the license header come from? It does not matter. You can change
 the whole header to look different, get it from other files, and so
 on, as
 long as the GPL preamble and the copyrights are there. So adding in
 headers is no violation as long as you know the code is GPL.

 Wrong. Bob's copyright is a copyleft, fool. Show any proof that
 there is
 something against decompiling GPL code. You cannot find any. 
 This isn't about decompiling GPL code. Its about decompiling a binary
 that was released, without source, in violation of the GPL. (Please
 tell me you remember that Bob was VIOLATING the GPL? Please?). He
 SHOULD have licensed his modifications under the GPL but he DIDN'T
 (remember?) which means you don't have a license for the
 modifications. 
 
 Whether he wanted to or not, use of GPL code makes it GPL code. That
 is
 the viral nature of GPL. End of story. Not putting out source or
 including
 the license files does not make his changes/code not be GPL. I think
 you
 are thinking too much in the vain of convention copyrights. The code
 is
 automatically GPL by way of use of other GPL code. It no longer is
 some
 independent proprietary code solely belonging to the original
 copyright
 holder once mixed together.

 You are talking complete and utter crap. Goodnight.
