I would encourage you to read the paper and book in that last frame to see this in more detail (links are here), but they talk about how you totally can use anthropological knowledge, but it's useless and reproduces colonialism if you don't combine that knowledge, critique or none, with material changes for the communities they're about. Decolonization isn't just a metaphor for academic purposes, and if the communities that have been "anthropologicized" aren't given autonomy, land, and some form of reparations, all that "decolonization" is for nothing. It's basically a riff on Marx's famous declaration "The philosophers have only interpreted the world, in various ways. The point, however, is to change it," but applied to a colonial context.
