| big words, unfortunately little common sense. I can give you some scenarios: - Practically every school (elementary school) in Germany uses WhatsApp for communication among Parents and Teachers. If you don't have WhatsApp, you have go to the school and read the official announcements in the wall. Lot of important information there, for example Teacher short-notice absence, protocol from meetings, etc. - The favorite communication channel of my university is via Whatsapp. There are lot of tools to consolidate and do the customer relationship via WhatsApp. - Back in the normal days, every single airbnb host that i contacted, were using WhatsApp So to make it clearer, the main difference between all IM listed are: - the user base itself (two billion users for WhatsApp[1]) - The number of 3rd part tools offering integration with that tools (zendesk, salesforce, etc).
