I think indigenous groups are largely unhappy with how much their culture and practices have been commoditized and sold to those outside their group as it is.
Aren’t Europeans, and many Asian ethnic groups considered an “indigenous group” of their home country. In such a case I don’t think say the Japanese are pissed off on the exportation of their culture through anime, etc.
To make such a general statement seems weird. Given the diverse nature of such a large number of groups.
fwiw I think an important distinction is that you're talking about a majority group. It's probably different for the indigenous people that the Japanese Empire committed genocide against, like the Ainu
Most of the indigenous people who I have met want to share their culture and are okay with earning a living by selling art that reflect their culture. They do not like it when others do the same, most likely due to a history of cultural misrepresentation, exploitation, and outright theft.
