Correct me if I'm wrong but aren't generalized wording releases (those that don't specify a specific use or instance) somewhat like general waivers of liability where the courts have ruled you can't give a waiver when you don't know the risks? In the example I used, the photo, taken many years ago was used in a billboard ad promoting same sex marriage. 20 years ago that type of use would most likely have been considered defamatory, but in today's society not so much. Likewise certain use 20 years ago depicting acceptable racial situations, could now be considered defamatory.
I'm not sure you understand that it's the publisher of an image with
recognizable people in it that needs a model/property release.
The photographer only needs a release
if the photographer is the publisher, but depending on how the photograph was made the photographer may not need a release for self-publishing and self-promotion of the photographer.
It's pretty rare to need a property release.
If the photographer sells an image with people in it to a publisher, the photographer is not liable for how the publisher uses the image.
Note however, that if the photographer does have on file a valid release that covers the publisher usage - the photo has more value.
When making people photographs out in public on location, model release law is such photographers can self-publish those photos to advertise or promote their business without the explicit permission of the people in the photos. When photos of people are made in private photographer do need permission from the people in the photos.
None the less my contract had a release clause that said the client allowed
any commercial use of their likeness, in exchange for a discount on the cost of my services, regardless if the photos were made in private, or not.
Clients had the option of opting out of that clause. Of course if the opted out they lost the discount and had to pay full price.
