One of the most shameful incidents in Utah's history. Not long after signing a treaty to respect the native lands and rights, the settlers, under orders from Salt Lake, almost entirely exterminated the tribe, killing dozens and either driving off or enslaving the rest. The chief's wife died up Rock Canyon trying to flee from the militia, who were hunting down and murdering the survivors. The word Squaw was used as a derogatory term for native wives

So yes, it's not surprise that various Native American groups find it offensive. Some of the comments about the name change amount to, "We don't care what you find offensive because our ancestors killed yours and took their lands, so we really don't give a crap what you think or want."
