Thank you all for shining a light on this. I didn't know this was so bad. I'm simply annoyed that some social groups use Facebook to organize, our neighborhood group, the parenting class, so I just can't be a part of that and try to move individual people, like my immediate neighbors, onto other platforms. But "bills, ordering food, govt services, parent teacher communications", that's extreme.
At least for bills and govt services I wonder, who approves something like that?
My kids' school has 3 different learning management systems (not integrated, BTW) to which students need to submit their homework/assignments. Well, at least in theory.
In practice, parents take photos of homework and send them to teachers via Whatsapp completely ignoring a formal system maintained for that purpose. Poor teachers have to save the time to upload files from their phones/computers to the system later and keep things organized from school's internal perspective.
I thought about proposing to school's IT that they changed the process, allowing parents to email files to a certain inbox, which an app would collect the files later and push them into the system automatically. I ended up not going ahead with the proposal because I already knew their reaction to me: "Whatsapp makes the process simpler".
