mpicpp sends news that Twitter is suing the U.S. government to fight their rules on what information can be shared about national security-related requests for user data. Service providers like Twitter are prohibited from telling us the exact number of National Security Letters and FISA court orders they've received. Google has filed a challenge based on First Amendment rights, and Twitter's lawsuit (PDF) is taking a similar approach. Twitter VP Ben Lee says, "We've tried to achieve the level of transparency our users deserve without litigation, but to no avail. In April, we provided a draft Transparency Report addendum to the U.S. Department of Justice and the Federal Bureau of Investigation, a report which we hoped would provide meaningful transparency for our users. After many months of discussions, we were unable to convince them to allow us to publish even a redacted version of the report."
