Earlier quoted context omitted.
I can't see the original issue, but it's interesting that the title chooses to highlight the fact that the GPL code was modified . Actually, under the GPL, this fact is immaterial. If the Winamp player contained any GPL code at all, modified or not, then it is a derivative work of that GPL code and anyone receiving a copy of Winamp is entitled to demand the full corresponding source be provided under a GPL license.

That's just not true, surely? Lest everyone using any flavour of Linux is liable to the same problem? How many apps out there are…
If by that you mean, if you are using Linux in production servers: You may use GPL software in a commercial setting. The source code part only applies if you are distributing software that contains GPL code.
