The point isn't about Nvidia graphic cards, but rather, the Nvidia-backed website that is being used to generate false personalities on the fly (and what people can do to avoid being tricked by the technology): https://thispersondoesnotexist.com
That website isn't "Nvidia-backed". It's created by a private individual—Phil Wang[0]—who happened to leverage a piece of free software Nvidia produced called StyleGAN2[1]
Furthermore, "false personalities" is something of a stretch for fake photos. There are plenty of "real" photos of people that haven't appeared on the internet, and even for the photos that have, most people will be fooled regardless. Generated photos don't change this: those making false representations are the only ones at fault here. Technology doesn't change this in any way.
There are also plenty of these ___doesnotexist.com websites, and they would continue to exist without Nvidia.
