When people have means to consume or produce content without control any governmental bureaucrat will try to control this activity. History supports this argument.
No printing press > no cheap books > illiterate population > easy to control what spreads as information and what do not.
Printing press arrived > cheap books > growing literacy > control over the presses. Lenin's first targets were the post/telegraph (communication), bridges and railways (movement of people) and all big printing houses (Lenin's Full Collected works - vol. 32, page 282)
Radio arrived > Fixed Frequencies Radio sets sold & Governmental Radio jamming stations
TV > Licence to broadcast
Internet > Big Firewall of China & etc...

The cost of enforcement in digital economy is way cheaper than before. The tools are there or can be built cheaply and sadly they're only built one way, from the government to the people. Open governmental data and strong society control over governmental actions is almost non-existent. "Brave new world" is here.
There should be a way to support important open-source projects with fundraising drives for features and etc ... Open source is one of the very few ways to sustain important digital freedoms.
