No, this is accurate, because, since as the natives state, colonialism was terrible for them, because they needed the nothing to survive, and the spread of western civilisation was a serious threat to them.
Where you assume something inaccurate to be doesn't imply inaccuracy of the source material, but rather the possibility of a different interpretation you might not have thought of beforehand. The intent of the posted material is meaningless in this situation.
When such interpretatiin does not exist, only then can an inaccuracy be declared. When the correct interpretation is seen as wrong by the uploader, it's just that their support of the claim has backfired.
