Probably threatened with a lawsuit by NPD
They sent an email and politely asked, while pointing out that GAF was giving away their intellectual property for free. Evilore then contacted the person and worked out an arrangement. I don't see anything wrong with that.
GAF got busted, and if they played the "We didn't know we were stealing your property card" it wouldn't have worked. If a lawyer got called in, GAF would be screwed. There's really nothing that could've been done to handle the situation, and I do think it's kinda cool that NPD has made some concessions, even if they are half-assed.
We got busted with our hands in the cookie jar, that's that.
