A while back (6 months? more?) Facebook tweaked things so that only game players see game updates in their feed.
Overall the article dramatically undersells the work that Facebook has done to improve the feed, mainly building off of signals you give it via engagement - I don't see updates from friends that I don't care about, and fairly rarely miss important updates from those that I do care about.
I could see how someone who only uses Facebook rarely wouldn't get that impression of improvement, as they will have given the algorithm very few inputs to work with.
The problem with the filtering is that it isn't transparent. Updates from people I'm actually interested in don't show because Facebook's feed algorithm thinks we don't interact on the site enough, and there's no mechanism to correct it or even let me know I've missed something.
Perhaps it's been fixed more recently, but I found that incredibly annoying.
