Which tech companies can you trust when it comes to protecting your privacy from government intrusion? Not Snapchat, not Amazon and not Comcast, according to the Electronic Frontier Foundation's (EFF) fourth annual "Who Has Your Back" report, released last week.\n\n\n\nThe fact that these companies made the Bad Guys list isn't much of a surprise. What is surprising though, is that Facebook, often maligned for playing very fast and loose with personal data, comes off looking very good, along with Google and Microsoft.\n\n\n\nAll three of those companies (and six others) received a perfect six stars in the report which gauges how hard companies fight to protect users' privacy from government data requests. That\u2019s not the same as refraining from vacuuming up your personal data to help sell ads.\n\n\n\nHere are the six categories used to judge the companies: 1) requires a warrant for content; 2) tells users about government data requests; 3) publishes transparency reports; 4) publishes law enforcement guidelines; 5) fights for users' privacy rights in courts; and 6) fights for users' privacy rights in Congress.\n\n\n\n"The sunlight brought about by a year's worth of Snowden leaks appears to have prompted dozens of companies to improve their policies when it comes to giving user data to the government," said EFF Activism Director Rainey Reitman. "Our report charts objectively verifiable categories of how tech companies react when the government seeks user data, so users can make informed decisions about which companies they should trust with their information."\n\n\n The point about the Snowden leaks is very important. Whether you think the one-time NSA analyst is a traitor or a hero, it\u2019s altogether clear that the revelations of a vast spying operation directed against Americans, as well as foreigners, changed the conversation about privacy in the United States. Not too long ago, Google was one of the very few, maybe the only, major tech company that routinely issued a transparency report detailing requests by the government for user data. \u00a0Now a lot of companies do. (You can read much more about Snowden in a new book by Glenn Greenwald called \u201cNo Place to Hide.\u201d You can also read my review of the book here.) \n\n\nIn 2013, the EFF awarded six stars to only one company: Sonic.net, a small ISP based in the San Francisco area. This year, Apple, Credo Mobile, Dropbox, Facebook, Google, Microsoft, Twitter and Yahoo (along with Sonic) all received six out of six stars.\n\n\n\nIf you look at the chart in the report, you see that the first two columns are really key: "Requires a warrant for content" and "Tells users about government data requests." Neither AT&T nor Comcast pass muster in that category. Amazon does ask for a warrant, but does not tell users about data requests.\n\n\n It\u2019s good to see these companies finally grow some spine, but it\u2019s worth noting that until foreign technology buyers started avoiding U.S. technology sellers because of fears that their products were not secure, Silicon Valley was a lot quieter about this.
