Calling this "gross" infantilizes both you and the issue. People jerk off and fantasize about others, and this is obviously going to be a great tool for that. The obvious issue is a lack of respect for another person's privacy and dignity, which is interesting, but probably a losing battle simply because the demand is out there. I do not think a comparison to something like CP would be appropriate simply because CP is naturally repulsive for most people, whereas seeing an attractive celebrity naked is naturally appealing to most people.
I chose "gross" because I suspected it would be a common reaction among many (not tech savvy) people.
I'm not sure how I feel about pornography in general. I suppose I prefer that it not be main-stream though — preferring that it hang back with a kind of false modesty.
That would run contrary to my experience. I've found there to be a huge pseudo-morality obsession with things involving sex/gender among middish age tech types, which porn gets wrapped up in, whereas the average person (outside of those who take their religion seriously) tends to have a more liberal attitude towards it.
But, that said, I actually agree with you. I'm certain that porn becoming so extremely main stream, to the point that pornhub's little audio theme or color scheme are essentially memes, is probably not a great thing overall for a healthy society. On the other hand I think it's probably inescapable. If one step's outside Western focused porn sites, there's a ton of porn even coming from places like Iran, literal morality police and Islamic fundamentalism notwithstanding. And I'm pretty happy with my relationship with porn, speaking as somebody married with children, so I don't see why that's unreasonable to expect of other people. Perhaps I'm simply falling into that 'middish age tech type' trap.

As an anecdote, I remember one of my first computers was a (rather dated) original IBM machine with an integrated ~6 inch monochrome green screen. In learning how computers worked at the time I was running essentially every *.com file. And one of them was... yip, 'porn.' It was a program with an innocuous name, tucked in the operating system directory, that would display some rather nice boobs made out of ascii characters on a 80x25 character display. I enjoyed that program.
