Not to mention the erosion of the idea that it is default-safe to share your social experiences with your group of "friends." Adoption by colleagues and family shifts the tone considerably towards LinkedIn, where one's professional image is paramount - and all that does is make the platform more stressful to use.
Facebook does provide tools to segment one's friends into groups to whom content can be privately posted, but from a UX perspective they're deemphasized. I see a lot more social conversations moving to group chats (some on Facebook Messenger, some on GroupMe/WhatsApp and the like), because membership is determinate, you make the choice of target audience before being prompted to make a post, and the context into which you post is not a newsfeed (which we've been trained to think is global to an entire circle of friends) but just that specific chat history. (I'm sure there's some psychology/UX research in that people don't intuit that a "posting destination" can be distinct from the list of content you're viewing.)
Chats are just a "safer space" to be oneself. And if Facebook wants to capture one's true self and preferences, it will need to evolve beyond the idea that a single newsfeed is the place people want to do that.
