about this: "(Pff! Unless your project is called "We're like Stockimage.com, but different", I doubt this is a concern)"
That's correct, but if you publish your game including a picture form there and you set the license to CC(whatever), you already have trouble. This new license allows people to publish the picture on wallpaper platforms or somehting like OpenGameArt for example. Maybe you don't publish it there yourself, but someone else does and gets trouble,you maybe get trouble too because you stated that this picture is CC-BY what it is not ...
CGtextures already attacked people who just tried to publish snippets of there pictures under an open source license for this reason and cgtextures had a very similar license back then!
As noone knows whats in their mind this new license may rise trouble easily.
"abuse" in their meaning is that those pictures are published or even sold on other websites. This is allowed with CC0 and they don't like it. Thats basically all.
Other websites like CGtextures made many trouble in the past and those had similar license types. "Unmodified" as they state it is not very safe, modifying one pixel is maybe not enough and so on.
And those other new restrictions are also not compatible with open source licenses.
