Why do many people dislike being photographed?

Afraid of being exposed, for example, many places in the west are in conflict, but you should be talking about some big cities, mostly some popular tourist attractions. They have long been used to being photographed and won't care too much. Most of them shoot scenery, so it doesn't matter. I don't care much about you. Of course, they are big-hearted and don't care much about others. They met foreigners several times in China and went to say hello and chat with them, but they didn't hold back. They even just said "thank you" and came to China to play alone.
