In an interview with the Guardian, Brin warned there were "very powerful forces that have lined up against the open internet on all sides and around the world". "I am more worried than I have been in the past," he said. "It's scary."
The threat to the freedom of the internet comes, he claims, from a combination of governments increasingly trying to control access and communication by their citizens, the entertainment industry's attempts to crack down on piracy, and the rise of "restrictive" walled gardens such as Facebook and Apple, which tightly control what software can be released on their platforms.

I personally find his comments a little more than a rant. Considering that Facebook is the main competitor to Google+ and Apple's iOS is the main competitor to Android. Though it is true that Facebook is quite rigid and closed and apple is dictatorial WRT apps for the iOS, but so is Google, when it forced android developers to use Google Checkout.
The article further says:
Brin said he and co-founder Larry Page would not have been able to create Google if the internet was dominated by Facebook. "You have to play by their rules, which are really restrictive," he said. "The kind of environment that we developed Google in, the reason that we were able to develop a search engine, is the web was so open. Once you get too many rules, that will stifle innovation."
and...
Ricken Patel, co-founder of Avaaz, the 14 million-strong online activist network which has been providing communication equipment and training to Syrian activists, echoed Brin's warning: "We've seen a massive attack on the freedom of the web. Governments are realising the power of this medium to organise people and they are trying to clamp down across the world, not just in places like China and North Korea; we're seeing bills in the United States, in Italy, all across the world."
So, does he have a point or is it just a pointless rant?
