Maybe, but already two years ago, if you read the fine print for ex. by buying a ticket for Cirque de Soleil you accept they can use your face on the video for ai training.
Except there you were shown the agreement and had to click or whatever.
For event tickets, you are not even made aware there is an “agreement “
But somebody did buy the ticket for you. Today you accept a lot when buying a ticket. Mostly you accept also to things like, they can use your picture on commercials / media and so on. Just the next time, take the time and read the full EULA when buying a ticket from a large event.
