Facebook will position itself as a provider of government digital services
Well, they do seem to have a shared goal of "get every bit of data on every single person in society and use it for questionable purposes", so yeah why not.
Facebook like money. The Government like pissing it away on "IT projects". Facebook are good at storing/processing huge volumes of data. The Government have no idea what data is never mind how to process and store it. Nobody really trusts either.
Seems like a match made in heaven!
