Living in a third world country right now that's rapidly developing. This is almost exclusively a smartphone-only internet society: "the internet" equals to Facebook, Youtube and Skype. Maybe some Clash of Clans, but that's it. There is no desire to open a web browser.

I don't see this changing any time in the future, either. There are still a lot of people without decent internet access here. I am pretty sure nearly all of these people will use Facebook's version of the internet, were it made available to them.

And don't have any illusions: there is no such thing as "net neutrality" here: internet speeds for domestic internet is way faster and cheaper than "real" internet. People have domestic-only internet plans, simply because it's all they need. So there already is massive restrictions put on the internet here, and I would argue that internet.org is not as evil as the local ISPs are.

Smartphone/app only internet is completely different from desktop-centric internet like it is in western countries.
