Sassy Justice was fun despite being a slightly low quality deep fake compared to recent standards. I liked it because it was the joke, rather than trying not to draw attention to the fact that it’s all fake.
Same thing they did with South Park (and Team America). It allows for more comedic freedom because you can always fall back on the defense of "this is just some stupid crappy thing, how could you possibly ever take it seriously".
I believe the parent commenter's point is that nobody is going to confuse these caricatures for the actual people. There will be many nefarious uses for this technology, but this is not one of them.
