This is good because it might make people question what they read on FB, but the reality is that (a) the whole digital economy is based on that. FB are no better than Google or Apple (who know where you are, right now!) or a miriad others (b) FB serves some purposes (my old aunt wouldn't be able to work out email, but FB is easy enough for her, for example) and (c) it seems that the trend is away from 'public' platforms like FB and towards non publicly accessible groups such as WhatsApp groups (also owned by FB..) or Telegram or Snapchat etc, so an anti-FB backlash may not achieve much in terms of a "healthier public discourse"

Also, it all depends on how you use it. I subscribe to a lot of food based groups and art events groups, and share next to nothing about what I do. OK, some AI can infer that if I like Lebanese AND Mexican I am probably left leaning. OK, now what? What are they going to do with that info?
