'It's the design that sells the mesh. So you can understand if Lockheed get a bit pissed if the merchant copies or bases the design on one they have copyright of.'

It's already been pointed out that their 'design' has already been paid for by the US taxpayer and we don't even have to go into the aspects of collusion between defense contractors and the government in the first place that ensures that they are always well compensated for their designs.

'The entire thing does get ridiculous when one contemplates it.  Here's Lockheed, making billions and getting Federal government contracts (guess where the government gets its funds - hmmm) and they are squashing a few people making probably, oh my, a couple thousand dollars selling 3D model representations without direct trademark infringements (logos and names and such).  Once again, big business making a point to go out of its way to step on an anthill.'

That sums the whole situation up nicely for me.
