Yeah, this 100%. Was talking with a couple friends about this very thing at lunch yesterday. About how social media companies have learned that the angrier people are, the higher the engagement number get, which means more ads pushed and thus more profit for them, so they deliberately work to foster the whole echo chamber mentality and then push those people together to make the sparks fly.

I seriously doubt the polarization thing is going away anytime soon. Not until something fundamental about these companies changes.
