There was a post I saw from an actual Egyptian about "appropriating ancient Egyptian culture", and they pointed out how Egypt profits heavily on the tourism industry, and that selling these symbols as aesthetic commodities for foreigners encourages foreigners to spend money on Egypt. They said what Egyptians actually care about is other countries taking authentic artifacts and not returning them to Egypt, since, while no longer part of their culture, it is part of their history.
It seems to me that when it comes to cultural appropriation, there's a huge divide between those who grew up and are living in the West and those who live in the country of origin.
