I understand your pov. It's true that censorship on Bing's image generator can be frustrating. However, there are also many reasons why this is happening.
1-) Bing's investors would likely be unhappy if the image generator were used to create images that are offensive, harmful, or illegal. Advertising could also be negatively affected if Bing were associated with an image generator that is used to create inappropriate content.
2-) Many users do not want to see images that are offensive or harmful. Censorship helps to protect these users from distress or even physical harm.
3-) Censorship can help to protect the personal safety of people. For example, if someone were able to create a realistic image of a famous person, that image could be used to deceive people or to steal their identity. As for the photos of Henry Cavill, it's true that they look fake. However, even fake images can be harmful to people. If someone were to create a fake image of a naked person, that image could be used to embarrass or humiliate the person. To dehumanize them.
4-) Censorship helps to protect children. Children are especially vulnerable to harmful or dangerous content, and censorship helps to keep them safe.
5-) Censorship helps to protect Bing's reputation. If Bing were associated with an image generator that is used to create inappropriate content, it could damage the company's reputation.
If I just turn the safe search off and ask bing image search for "extreme gay fisting bdsm" or "Hillary Clinton fake porn", the results I get are apparently fine for Bing reputation and children. But if I go instead to Bing image creator and ask for "A young woman in a bikini dances in front of her male friends, view from behind", I get a red message menacing with suspension. Thanks censors, children are safe!
I shared an image yesterday for the first time in this thread, of a male exotic dancer. Just mildly erotic. I posted here the prompt, that I tried several times along the last few weeks. Today I checked the same prompt and it was flagged. This is probably just a coincidence, but it makes me feel under the scrutiny of a mafia. I feel discouraged to continue sharing.
