"The exact same story is true for WhatsApp, Twitter, Instragram, Google Plus, Google Drive etc. We could have replicated a lot of stuff, but the service providers didn’t allow us to. WhatsApp allegedly wanted a seven-figure sum to just allow access to the API, not for developing a working client app. Instagram locked down their API so much that the built-in Instagram Scope had to be removed. Google doesn’t even have a public API for many services."If you're going to build this type of system then the internet services also need to be freedom friendly. An Ubuntu phone and maybe an Ubuntu home or business server might have been something which could be sold as an integrated system delivering services without the lock-in and in a way which could be supported by the non-Canonical developer community.
