We see the consequences of a non-open Internet every day where we work in Uganda. It is common there for people to have "social bundles" that only work for Facebook, WhatsApp, Twitter, etc. Our users believe they have Internet access but don't understand why data from our app is not syncing when Facebook is working. It's a large barrier for us and adds a huge moat for the incumbents. We're considering more integration over WhatsApp or Facebook Messenger so we too can benefit from the cheaper data but that only locks us into those platforms and strengthens their position.
