1. The monopolies literally make no money - WhatsApp is run at cost and doesn't turn a profit.

2. You are not gonna have universal phone-number based messaging that is E2EE without a monopoly. Even RCS has monopolistic gateways. Decentralized/federated systems suck and don't easily work with phone numbers.

3. If you keep breaking up chat applications as soon as they reach a certain size, you're not helping consumers in any way. People use WhatsApp because it's good, reliable, and E2EE. Breaking it up provides literally no value to consumers.
