It can certainly be seen as problematic.
I said something on a Daily Kos thread about loving my curly-toed slippers from India. Another poster said she’d only wear them were she from India herself, and mentioned cultural appropriation.
I did not reply, but reckoned that had the seller wanted only fellow Indians to buy and wear them, their goods would only be available on ebay dot IN, and worldwide shipping would not be offered. 
Cultural appropriation is wretched. Learning about, respecting, and enjoying items and aspects of other cultures is the opposite. I can’t even begin to imagine the blandness of my life had I stuck only to modren European culture, and American culture, whatever TF that means. 
I have watched lotsa videos of Central and South American makers, vendors, and owners demonstrating their death whistles. Mindblowing, spooky stuff! They are amazing!

Not to sound too new age crispy, but those low frequency tones really do go straight to my third eye. Live, they might affect me like heavy bass normally does at shows w/conventional modren instruments, pounding on my chest and belly.
