I don't know details of this case but it's very unlikely GS was violating any FOSS license for just modifying code (assuming internal use only).

I think I see your point, but I wonder... do GS distribute code to their employees? To partner organizations? If so, what are the terms of that distribution? If they are anything other than the original license requires, that's a violation.

Oh noes, now we can't have nice things anymore...

I suggest you read the GPL faq which should help clear up some of the issues for you:
