Dealt with this issue my entire career in TV news. It's a balance. If you are out in a public place, and can be seen without a telephoto lens with the human eye, you have NO expectation of privacy and you can be photographed. In TV news, if someone asks that you not show their face, certainly that request will be considered, but it is not a request has HAS to be honored. The law is pretty clear on that.
HOWEVER, what I have posted about myself recently that I can see being an issue is with YouTubers who make their living off the videos they post, and photograph people in what I would consider to be a "private" place posting videos and pictures. And they are NOT news media, and to me, photographing a woman in her bathing suit on a cruise ship is NOT a public place. That is a situation where permission would be required and a signed release necessary. I watched one You Tubers video and he was on the pool deck and recorded a woman in her bathing suit getting out of a hot tub, walking towards the camera, seeing the camera, looking distressed and briskly returning to the hot tub so she could not be photographed. That video was posted by a youtuber in a ship's tour video, and I think that is something he should have edited out because he was not in a public place and the person he videotaped clearly was uncomfortable with it.
