BITO was uninhabited before it was settled by Europeans. It doesn't have "native people" according to Wikipedia. Unlike .us/au/ca etc. Are those tlds controlled by their native people?
> On 22 May 2019, the United Nations General Assembly adopted a resolution [...] demanding that the United Kingdom unconditionally withdraw its colonial administration from the area within six months.
The Chagossians aren't a counter-example to that at all - they were moved to the islands by European colonialists as a slave labour force, which as I understand it were uninhabited before.
What, did you expect a new lineage of humans to evolve separately there or something?
Of course "native" can be arbitrarily limited to mean 1000s or 10,000s of years, but even after slavery those people lived there for at least five or six generations. So from the perspective of the people being forcibly removed, getting their pet dogs gassed by the military, it really wouldn't fucking matter.
And the Wikipedia article says they're "native", which you explicitly claimed was not the case.
