You can _almost_ do anything you want in the privacy of your home; but in this case Twitter was actively and directly disseminating pictures publicly on their platform.

And profiting from it, though less directly than "$ for illegal images". Even if it wasn't behind a paywall (which it mostly is) driving more traffic for more ads for more income is still profiting from illegal imagery.

Is twitter a piece of paper in your desk? No, it's not.

Right.

OP had "It has always been illegal and morally reprehensible to create, own, distribute or store "

It would make more sense then to instead say:

"It has always been illegal and morally reprehensible to distribute "

Again, AI deepfakes are not sketches in a piece of paper. There's a massive difference between drawing your coworker naked on a piece of paper (weird, but certainly not criminal), and going "grok generate a video of my coworker bouncing on my d*ck". Not to mention the latter is generated and stored god knows where, against the consent of the depicted person.
