The Technology Of Free Speech
"Free Speech" is a bit like pregnancy; you either are pregnant or your not, and you either have free speech or you don't. It can't be "kinda free". Technology has often been put forth as a great "leveler", by bringing information and ideas to everyone, often via the Internet.
Recent revolts in foreign countries were documented by people on the street using cell phones and posting videos on YouTube or eyewitness accounts and photos on Twitter and Facebook. The signs are that this golden age of freedom may quickly be waning.
Governments are onto Google's potential to allow unwanted information to get into and out of the hands of their populace, and are working to block access where they can, or even just attempt to shut off Internet access during times of political and social upheaval.
Even in Australia, the two largest ISP's - Telstra and Optus - are soon going to start voluntarily censoring website access. The laudable intent is to block access to sites involved in child abuse or child pornography.
Away from the web itself, Apple has filed a patent for a camera system that can be shut off by a third party - the practical application of this could be used to prohibit camera owners from taking pictures at concerts, for example.
In all of the above examples, one can see the potential of a "slippery slope" towards more widespread and arbitrary censorship of different aspects of technology by governments or other entities, which is not very encouraging for the future.
