Is it o.k. if people don't think the Internet doesn't exist?

At Davos this year, Sandberg told the well-heeled crowd (paywall) that in the developing world, “people will walk into phone stores and say ‘I want Facebook.’ People actually confuse Facebook and the internet in some places.” Or as Iris Orriss, Facebook’s head of localization and internationalization, has put it, “Awareness of the Internet in developing countries is very limited. In fact, for many users, Facebook isthe internet, as it’s often the only accessible application.” (Emphasis in the original.)

Scary. That's like thinking Ford's are the only type of vehicle. This has massive implications - what if every service was to move onto Facebook, giving them total control through the impossible-to-make-sense-of filtering News Feed? You only see what the filter decides it wants you to see....... At least by people searching through something such as Google, Bing or DuckDuckGo, you choose what you want to search. Thoughts?
