Web freedom faces greatest threat ever, warns Google's Sergey Brin | Technology | The Guardian: He said he was most concerned by the efforts of countries such as China, Saudi Arabia and Iran to censor and restrict use of the internet, but warned that the rise of Facebook and Apple, which have their own proprietary platforms and control access to their users, risked stifling innovation and balkanising the web.
"There's a lot to be lost," he said. "For example, all the information in apps – that data is not crawlable by web crawlers. You can't search it."
