EDIT:
Let me go ahead and put emphasis on "slowly".
As waterlesscloud points out, right now it's very uncommon.
The only reason it's on the agenda at all is because there's been headlines about insane employers asking to see employees Facebook profiles.
Libertarianism being the dominant political philosophy of the moment such encroachments seem inevitable.
I fail to understand how one could look at the events of the last decade and determine that the major problems are that people have too much freedom and government has too little power.
