By posing, they pander to that hero worship and ,no doubt, feel good. OK, that is human, but they are supposed to be above that. In the old days I suggest such a request would be politely declined.
Not sure about that. Over the years I've seen several snaps of people with old GB members.
The biggest differences are that (a) they are recognised and (b) everyone has a camera and is not shy about using it.
Until the current crop put themselves on telly they could be far more anonymous. I agree that they could choose not to have a photo but the fact that they do is not proof that they seek fame in itself.
