On the real, are they really just going to spell tribe names with random Greek letters and numbers and pretend that’s totally normal?

To be completely fair - these are the original language transcriptions of their names using a phonetic spelling system (e.g. https://en.wikipedia.org/wiki/Squamish_language), as opposed to the Anglicized versions afterwards and that we are more familiar with. There's a lot of stupidity about the land acknowledgement thing, but this isn't one of them. A comparison would be calling Russia "Россия" instead of "Russia".
