Exactly that – it’s become full of mindless drivel and adverts for things it thinks you might be interested in, be that people, applications, products or services.
I recently spent an evening unfollowing all the companies I’d “liked” in the last 7 or so years. It complained quite a bit about this and even tried to put a stop to my actions after about an hour. The end result, once it relented, is that I’ve now got a news feed which is predominantly about people that I actually know and like to hear from, a bit like it was 5 years ago.
