Yes, of course. But who is referring to non-Inuit as Inuit? Unless I've missed something, your point seems to have to do entirely with some reported statement emanating from the Inuit Circumpolar Conference, which perhaps was understood by those who made it to have a limited application, e.g., for purposes of the Conference policy, legal documents, etc. As far as I know, I've never heard anyone use the term Inuit that broadly.
