Part of it is likely that she is a famous woman who is not known for being sexualized and is considered a public figure. No one wants to have the scientific standard be “I used pics of this girl I had a crush on” so I imagine famous people are good to pick from. I imagine Merkel also doesn’t have a lot of bikini pics AI can draw from (some amount of swimming pics are unfortunately always available for public figures for some reason) so you can be sure it’s generated them from nothing. If you used a famous model, there may be a possibility it is using pics of them to model their chest. If you’re testing what it does with random inputs, using Merkel is probably a good option.
As far as the output being what was requested, I think the issue can vary depending on your view of AI so I am just going to leave that part unanswered because if it’s a problem or not relies so much on your priors.
I’m a woman and not on tinder, but I don’t know why people don’t like this. Anyone listing a height preference is not the kind of person you should be looking for, especially if you don’t fit their preference imho. It’s literally self filtering, though it did say it’s not fully blocking or anything.
I know women who would’ve loved that feature and I would never suggest any of my friends date them. Even after they dated guys that didn’t fit the criteria and amicably split, they still held firm to the idea. I think it’s ok to have preferences, but this is dumb to filter for and people are dumb to want to match with these people.
