Facebook CEO Mark Zuckerberg called President Barack Obama Thursday expressing frustration over the excessive snooping being conducted by the NSA. Zuckerberg posted on his Facebook page assuring his followers that he plans to take the issue of government snooping very seriously and he wants to protect users from online surveillance. Zuckerberg has been an outspoken critic of the U.S. National Security Agency's online surveillance program, which was revealed last year by former NSA contractor Edward Snowden. "I've called President Obama to express my frustration over the damage the government is creating for all of our future. Unfortunately, it seems like it will take a very long time for true full reform," read the post. The post comes days after documents from whistle-blower Edward Snowden revealed that the NSA would pose as a fake Facebook server in order to hack into millions of computers. The documents were released by Glenn Greenwald of The Intercept. The Internet, Zuckerberg wrote, is a shared space that gives voice to people and makes communities stronger and safer. He said that Facebook tries to ensure that its services are secure and works to find potential security flaws. Zuckerberg added that he is "confused and frustrated " with the actions of the U.S. government. "The US government should be the champion for the internet, not a threat. They need to be much more transparent about what they're doing, or otherwise people will believe the worst," Zuckerberg said.
