This is just the latest reason that some people are leaving Facebook. In May, Facebook was one of several technology companies outed as a participant in secret U.S. National Security Agency domestic electronic-surveillance programs such as PRISM. Edward Snowden, the former NSA-contractor-turned-whistle-blower, reported that companies such as Facebook even worked with the NSA to provide backdoor access to user data. Facebook was one of the last companies implicated by Snowden to publish a transparency report about requests for information it receives from the government.
