I think there's a huge divide between people who recognize that TIV exists, and those who only see victim signalling as purely authentic, hence it's manipulative capabilities.
There's an Inuit signer [1] who is adamant that other aboriginals cannot do the 'throat singing'. The thing is - nobody cares that much about the art form, however, the CBC (Canada) and other entities will do some national coverage when they want to do 'Aboriginal Focus' because it's authentic and unique. This made an Inuit throat singer a little bit of a sub-star within the community. Along comes another Aboriginal doing it to steal some of the shine and the original lady went full into cultural appropriation diva mode.
I've never heard of an art form in my life, which almost nobody practices where the practitioners want to stop everyone else from participating because of very narrow and specific blood lineage.

This is 'power in victimhood' and using identity to garner social capital and leverage.
The challenge is, there is often some degree of kernel of truth in the matter - i.e. it's not a completely irrational argument to contemplate if people who are not from a certain culture do something very culturally specific, and this is how arguments I think can get populist. Similar to the situation wherein there is some kind of confrontation between a Black and White person, wherein 'racism' may have nothing at all to do with the situation, but since there is the possibility, it's held as though there is de facto racism on the news.
Finally, this is not to suggest there are not real victims. Those who can't see TIV exists will see all cynical reaction to claims of victimhood as straight up fascism or some kind of deep insensitivity when it may or may not be the case.
