Tastelessness aside, this seems perfectly rational to me. Unlike reverse engineering for the purpose of developing security exploits, "nudification" doesn't meaningfully expand the capabilities of malicious actors with access to free online porn and Photoshop.
That's one of the weirdest takes on here in a while.
I can develop security exploits myself just fine without the use of AI. Many people don't have the capability to use Photoshop and free online porn to deepfake someone else they might or might not personally know into a realistic video...
Actually violating one person is fine, but doing anything associated with a specific industry that has applications for harm and help is not?
That's like saying it's fine to beat someone up and take their lunch, but it's not fine to learn how locks work.
