This is a story from a few months ago, but although I couldn't quickly anything more recent, it appears to just be gaining traction on social media now - perhaps because the changes are only now being phased in?

Just so people know, the word "chief" comes from old French many hundreds of years ago (before the colonization of the new world in fact).
The French word "chef" at the time meant "head" as in the top part of your body. This evolved into "chef" and later "chief" to mean a leader who heads up something.
In modern French it's more often used in combination with another word, as in "couvre-chef" which is kind of a poetic way of referring to a hat or a cap.
Its origins at least have nothing to do with aboriginal peoples in North America.
