> The top comment mentions people hiding posts from pages they don't follow - alternatively, that's called showing brand new content you haven't seen before.

These were people who had already been sorted into echo chambers. Turning off the algorithm sent data to them they had already learned to hide. I'd be interested to see how this same experiment fared with completely new user. Maybe we'll run across a new tribe in the Amazon or something so we can try this out.
