I could imagine NV PR imagining explaining to joe bobs Gforce Heavan.com how it is they can't get a card (when of course they are the biggest NV fans in the world) when R3D is getting one.
I think Josh made a good point that might also be a path forward --buy your own NV board (or get one from a board partner --did you try that route? Lots more of them) and prove by the only way that matters that you'd do a fair review in that situation (by doing one).
I'm
pretty sure (well, y'know, 95%+) that NV wouldn't send in a SWAT team to liberate a board you bought yourself before you could review it. I think.
