It's the other way around. Governments are loosing power and are scared as little puppies. On the internet the meaning of "free speech" really comes to life. People share and talk openly about religion, sex and all similar "forbidden" stuff. We all have been raised as children with certain beliefs that our parents and elders told us. It was only through life experience and others points of view, that we could analyze these beliefs if they are true or not. Governments and religions are scared of seeing their nation think with their own mind. After all they have been injecting them their own beliefs and fears for generations. Knowledge is power and the big brothers want to keep it away from public. They want to keep people as slaves and weak. They want you to depend on them. Any restriction of freedom is the result of ego minds and no one should ever listen to such an authority.
In most of the countries websites violating the defence system are going to blocked. Youtube ok. its fine,
