It's not the photos that are the problem, it's that people don't really understand or respect others' privacy in the internet age.
February before covid, I was at a college in Manchester and was pleasantly surprised when they asked us to complete consent forms on where the photos that were to be taken were going to be uploaded. I was very happy to check the "I don't consent to photos of me shared on social media", consequently they took some photos with me & some without me. No pressure to be part of the group & not be left out.
