3) The entire surf rock movement of the 50s.
Laying sole claim to the Phrygian Dominant scale would be a half appropriation from other cultures that have made use of that mode for as long as the Jews.
I was listening to a NPR program yesterday where a cookbook author was interviewed--she had recently written a cookbook of Jewish cooking, from around the world and history. Even before the Diaspora, Jews were fairly widely spread, and picked up and appropriated all manners of cooking and ingredients--much was picked up from India and Babylon--and things picked up there originated in China, etc
Then post-diaspora the large merchant class of Jews emerged throughout Europe, moving goods and cultures--a huge factor in bringing new world crops and foods and recipes to Europe was through Jewish merchants. They essentially saw the value and demand for appropriation.
I think appropriation of these things (clothing, cuisine, music) is simply a matter of human curiosity and creativity.
I am also thinking of the very vibrant "food truck" industry, where people from, say China or Vietnam or Korea adopt Mexican recipes (and vise versa)or ideas and create something new.
I don't quite get the idea that people can or should put a lid on appropriation-- as if they can preserve culture like some museum specimen, or that simply by being born into some "culture" you are forever beholden not to step beyond the boundary that some authority set.
