And colonialism did not benefit Indigenous people.

“But we gave them technology!” No. You killed them and destroyed their culture. The few survivors learned your technology as a way to survive your reign, technology which you tried very hard to withhold from them as a means of dominating them. Indigenous people (and POC in general) were banned from attending university in the US and Canada until relatively recently for example. Stop acting like you gifted them technology out of the goodness of your heart.
