Facebook has a good message-distribution-thing going though. If you're a student, there's plenty of official and semi-official info-distribution via FB, WhatsApp etc. My local government uses FB more than their own Website. If you want to know whether you still have to wear a mask next week, you need to check FB. That's a strong value proposition, because you can opt out, but you're going to pay for it by not receiving information / receiving it delayed.
