I believe there are other instances of GPL being upheld in courts around the world and this one should be only one of many examples.
GPL is not even necessary in these cases, in the absence of the (GP) license it reverts to the default copyright rules, with all rights of copy and distribution being at the hands of the copyright holders (save for Fair use and other exceptions).
A company that would try to argue that GPL is not a valid license in court would actually be admitting in court that they are distributing the software without a license from the copyright holders all along.

Wont this end with BWM uploading a tar.gz of a kernel found on kernel.org and call it a good working day?
Have seen it happen too many times, and in most countries the user has no claim on the license/copyright.
So unless I contributed/own some copyright found in exact Linux kernel version/other software used by a distributor, and buy their stuff, there is zilch I can do.
Which also means, you are free to sell/and break GPL software/license and as long as you dont upset somebody who owns the copyright to it, you're good to go.
