Agreed here. I feel like I am constantly fighting to filter out all this "content" from external sites. I feel like I can't even see the stuff I joined FB for- to see pictures/updates to see what my friends are up to. Instagram is much better for this these days, the signal/noise ratio is getting so low on FB that I find myself going on just out of habit, not because of the information I get from there. It has shades of slashdot, which for awhile was just in my daily list of sites to visit because it always had been, eventually though it dropped off.
Note that you can eliminate a lot of this crap by changing your news feed from "top stories" to "most recent." This change will not persist, can not be changed on the app, and you will have to manually change this every time you log on- you can't even save the url as a bookmark. Still, its waaay closer to the FB I used to really like.
