I'll grant there is a considerable amount of information manipulation here in the US. Having spent a time working in and around our government and some of the things that are kept away from public scrutiny I understand first-hand there are reasons some information is kept secret.
That is not my point and was not the comment I was making. It was not about government information being kept secret - my comment was plainly about government's controlling what their people can do on a day-to-day basis. Take the actual content of the article discussing people having access to social media - that isn't controlling access to government secrets, it's controlling access to the outside world. Again, I also said if people choose to remain within the bounds of that control by choice, it's their choice (as you said "A lot of people like their government-imposed veils") but if not they should have the ability and basic human right to be free and think for themselves.
I could absolutely care less what deep-dark secrets of the inner-workings of the government want to remain veiled - that is up to their people to deal with as it is ours. I am talking about the proscribed birth-rate limits, the limits on what sex a baby can be, where you can seek information, what you are allowed to hear, what you can do to earn a living, etc. I am talking about basic freedoms. The same is said about slavery in the US but in the end the same truth was present - people wanted to be free. That has nothing what-so-ever to do with government manipulation of banking or insurance, nothing at all to do with the next weapon or how to infiltrate an enemy, it has only to do with the ability of people to make some of the choices in their lives for themselves.
At the end of the day my question remains. Does it really work? If it did would there ever be anyone trying to shrug off the yoke of control and manipulation? At the end of the day my question was really rhetorical.
