No, it doesn't and I was not implying that it was, sorry I
misrepresented the issue.

However, it is the view of Harald *and his lawyers*, as expressed by
Harald during the OLS BOF session and since they did manage to
successfully llitigate a case based on GPL violation in court their
views may or may not have some merit. They are something to consider
however, when you come to consider the matter.

I was trying to locate a copy of Harald presentation, but since it was a
BOF and not a lecture it is not in the proceedings and I couldn't find it.

As I said, I am simply bringing here the views of Harald, as I
understand them. I share your doubts in regard to the validity of this
approach but though it is worth while to advertise what others (with
court tested experience with the GPL) think.

Cheers,
Gilad
