@Brendanjones This! I haven't seen such a blatant breach of boundaries yet myself but I'm hearing all the time of teachers sending homework via private apps, schools having group chats on WhatsApp etc. It's unacceptable that teachers or other public servants force people to hand over their data and contacts to Meta or any other such company. I wish I had a way of preventing others giving these companies my contact info when they use the services, never mind using them myself.
