You're assuming "outside influence" is the same thing as "different views". For example, in information ops you only have to use sensemaking on a target (https://en.wikipedia.org/wiki/Sensemaking) to feed little bits of info or ideas that favor your goal. The end result is that the target feels protected from outside influence but it's anything but.

I didn't assume that. News bubbles give people a way to not be subjected to some external influence, which is not to say they are not subjected to any influence, it just makes a choice of which influence they are subjected to more random and different. Traditional media, on the other hand, being less bubbly and exposing everyone to their ideas favors money and gives unfair advantage to elites and not outsiders.
