Spot on. This is a perfect example of appropriation.

Cultural appropriation is the inappropriate or unacknowledged adoption of an element or elements of one culture or identity by members of another culture or identity. This can be controversial when members of a dominant culture appropriate from minority cultures.
According to critics of the practice, cultural appropriation differs from acculturation, assimilation, or equal cultural exchange in that this appropriation is a form of colonialism. When cultural elements are copied from a minority culture by members of a dominant culture, and these elements are used outside of their original cultural context ─ sometimes even against the expressly stated wishes of members of the originating culture – the practice is often received negatively.
