I don't use my Facebook much except to occasionally share vacation photos these days. Checking recently seems to show no news of any sort. Just some silly memes, weather phenomenon (supermoons!), pop-geek-culture stuff, and daily status updates. Since it's the season, there's some American football discussion, which people obviously have disagreements on, of course, but in that "sport" sort of way. :) I'm sure major news (like major weather events) will still make my feed, but there seems to be a noticeable decrease in political stuff.
My cynical take on this announcement is that, for those that post and share a lot of news, there is a high probability that your news bubble will be more heavily reinforced. Not all Trump voters are Alex Jones heads, of course, but if you are one, maybe Alex Jones will still be at the top of your news feed, and you will get all of the Alex Jones-y shares you want. It just won't be on the feed of the friend who prefers is apolitical merely sharing silly cat videos, or the person who is sharing Rachel Maddow clips. Facebook, in other words, will strive to bring you the best news feed that you will never disagree with, all the better for dopamine-inducing clicks and likes.
(I don't really know, of course, if my cynicism is off the mark, but these sort of opaque-algorithm news feed games Facebook plays are a large reason why I rarely use my Facebook feed. :) )
