There is a huge difference between active government censorship (China, Russia, etc.) and potential monitoring of internet traffic.

Aside from that very vast difference, it has always been possible for communication systems to be monitored. Telephone, telegraph, and postal services have always been able to be intercepted by law enforcement.

In fact I would point out that the very fact that the article you linked to about Room 641A exists, both in its creation and existence demonstrates that very difference.
