Facebook and Microsoft each fielded thousands of requests for user data from U.S. authorities in the second half of last year. The companies disclosed the figures in corporate blog posts.

The requests might include some under the Foreign Intelligence Surveillance Act, but they might not, Microsoft’s official says. The data does little to shed any light on snooping in the name of national security.”]
