I don’t think we can examine these things in isolation. We do have more and more news available to us than ever before but:

a) there are more other things than ever before too. Used to be folks would watch the nightly news because there were only four channels or so to even watch. Now you have endless options.

b) the competition between all the news options means that more of them are leaning into opinionated content that you’ll either identify with on a tribal basis or get outraged by, because that gets more views. Informing the public is a secondary goal.
