Bear in mind they were not in a public place, but a conference venue - which would almost certainly be private property. It is totally legal to prohibit photography in such cases.

However, normally this has to be made explicit (through signs, or the like) - it's assumed it is allowed unless otherwise stated.

I wonder if going forward conferences will consider banning photography in future, for better or for worse.

I'd be a little surprised.

The photograph doesn't seem to really be the issue, just an obvious thing that Adria did "wrong" for people to seize upon.

It seems like the exact same situation could occur if she had simply reported them through their names rather than through photography.

Thank you for the explanation, that clears a lot of things up around this topic
