Google, Microsoft, others backing Facebook in fight over user privacy in New York

Today, a number of major tech companies including Dropbox, Foursquare, Google, Kickstarter, LinkedIn, Meetup, Microsoft, Pinterest, Twitter, Tumblr, and Yelp, along with the New York Civil Liberties Union and the ACLU, filed amicus briefs in support of Facebook.
