How or why the developer may have ever thought otherwise is a mystery. In a lame attempt to justify the app's existence, the developer further stated that the software was created "for user's entertainment" and is "not that great, it only works with particular photos." Here is the full statement on why the app is no longer available...
"The networks are multiple, because each one has a different task: locate the clothes. Mask the clothes. Speculate anatomical positions. Render it," the developer told Motherboard. "All this makes processing slow (30 seconds in a normal computer), but this can be improved and accelerated in the future."
DeepNude only works with pictures of women. Though the developer considers it to be a "slow" process, the effect is much quicker than manually manipulating a photo in a similar manner in Photoshop. It is also way faster than what it takes to generate a deepfake video.
The ramifications for something like this are both creepy and frightening. This is the sort of thing that can be used for revenge porn, whereby in this case a nude photo of a woman could be posted without her consent. Though the naked parts are not the actual ones, it hardly matters.
"Yes, it isn’t your actual vagina, but... others think that they are seeing you naked," Danielle Citron, a law professor at the University of Maryland Carey School of Law, told Motherboard. "As a deepfake victim said to me—it felt like thousands saw her naked, she felt her body wasn’t her own anymore."
The DeepNude app represents one of the worst implementations for machine learning. Unfortunately, even though it has been yanked offline, the copies that are out in the wild still work. More over, the developer is probably correct that someone else would have (and still will) create a similar app.
