For most people, Facebook is the only place where they can stay in touch with their family and friends. My friends and family are not and never will be on mastodon or diaspora or anything like that. Also, private special interest groups on Facebook are really excellent. There's nothing else like it. Sub Reddits are good for anonymous/psuedonymous general discussion, but for actually meeting and interacting with people who share your interests, and especially for sharing pictures/videos, I haven't seen anything better than Facebook. I'm a member of several music related Facebook groups - they get far more high quality participation (and fewer flame-wars) than comparable old-school web forums.
