Unfortunately, many media outlets do not understand the differences and serve only to further confuse their viewers on the topic. The only source I would trust regarding any indigenous topics is APTN. The linked video briefly describes the differences between elected and hereditary chiefs in Wet'suwet'en law, though this may be different with other tribal law systems.

I will only add that the elected chiefs, representing their respective reserves, have a conflict of interest since the funding they rely on to provide for their people comes from the government, which is obviously not on their side. For them, it was either endorse the pipeline or lose funding from the government, which would probably mean losing their land.

Also, this video talks about RCMP disinformation tactics using the media to misrepresent the people who's land is being taken away as criminals.
