As much as I think Nvidia sucks for screwing over consumers with fake msrp prices and fake frames/MFG this is one situation where I don't think Nvidia would put backdoors into their gpus as it would hurt them more than it could possibly benefit them I feel.

I have no proof that they are or aren't putting in backdoors but from a system analysis perspective the idea of Nvidia implementing backdoors to get government money or tax exemptions, or whatever in exchange sounds quite silly as doing so would nuke their credibility entirely. Like not just for the consumer market but additionally the enterprise market.

Nvidia could say adios to consumers and exit the consumer gpu market entirely and still benefit from solely selling enterprise gpus and specialised servers. But they can't exit enterprise. It would spell the death of Nvidia as a whole.
