I don’t recall any open-to-the-public venue that restricts its *attendees* (1) this way, in fact, it appears that existing laws already do the converse. I.e., it’s a reductio ad legis (sorry if my Latin is rusty), i.e., “reduction to (existing) law”. Joe (1) to Mary’s point, AFAIR, photography releases at some events addresses use of those photographs by the venue, e.g., for promotional purposes. Having the ISOC assert or assure it won’t assert that permission without explicit consent is quite different. |
