The Problem with messaging today
The provider knows all about your social network: when you communicate, with whom, the frequency of your communication and the number, type and length of your messages – even with end to end encryption in place.
These networks are controlled by a single party. Developers cannot start hosting their own WhatsApp, WeChat or FB Messenger Service. Competition and innovation is blocked.
Users cannot easily change chat providers. If they want to switch, they need to convince their friends to move too. Also, they would lose their conversation history, groups, and more. Users are stuck: if they do not like something, e.g. a new app version, oh well: you can’t go anywhere else!
Service providers have to comply with the rules set by the messaging owner. If the messaging provider changes the rules or API, they are out of luck and must adapt fast.
Some large providers control many of the popular messaging apps. For example, Facebook owns both WhatsApp and Facebook Messenger. This makes it feel like there is no real choice.
Each network is closed and the users in that network are isolated. This means restricted movement between silos, no new innovation outside the controlling power, no new players, no resistance to attacks (single source code) and it simply goes against the philosophy of the internet: freedom, innovation and growth around the use of common standards.
