I'm not agreeing or disagreeing with your observations of news filter bubbling... BUT... I just thought of the analogy of music filter bubbling. Only a couple years ago when there was a big push for awhile for music streaming there was plenty of debate to observe along the lines of some people seemed rather horrified at the stress of having to select their own musical playlist where others were ready to go nuclear because they wanted to rock out to Pantera and some human or algo DJ insists on flooding them with Taylor Swift.

I don't even care which argument won in the marketplace for "music filter bubble" or even "news filter bubble" but it is interesting that very strong, perhaps equally strong, arguments exist for both.
