They are valid points; they do bad things with "diversity". I have seen such acknowledgements in Canada too sometimes, although I don't know if it is as bad as you describe there, because I do not know the details.

Better would be to actually avoid damaging the indigenous people and avoid damaging the land. What was done in the past is done, but you could avoid doing it again.

Saying stuff (especially stuff that doesn't even have proper good points and doesn't even help anything) is not a substitute for actually doing actually good things.
