gekrompen hoofd: I think if someone wanted to post a picture of Michaelangelo's David in a public place like a museum would be OK, but if you tried to take that photo to a private place like McDonalds (or private game site like this one), then that would be up to the owner of the McDonalds or private site of what should be allowed to be shown in their own private place.

Freedoms that are hinted at in your post have no place in a privatly owned place. (And BrainKing is still privatly owned and operated.)
