A collection of 10 technology companies, including big names in software, hardware and the web, have signed a letter of support for new legislation that would limit bulk metadata collection in the US.
AOL, Apple, Dropbox, Microsoft, Evernote, Facebook, Google, LinkedIn, Twitter and Yahoo have previously made individual appeals in favour of less government surveillance, but this is the first collective appeal.
The open letter to the US Senate asks the government to support the proposed US Freedom Act that would cover many of the issues raised in the wake of the Edward Snowden revelations
"The Senate has an opportunity this week to vote on the bipartisan US Freedom Act. We urge you to pass the bill, which both protects national security and reaffirms America's commitment to the freedoms we all cherish," they wrote.
"The legislation prevents the bulk collection of internet metadata under various authorities.
"The bill also allows for transparency about government demands for user information from technology companies, and [ensures] that the appropriate oversight and accountability mechanisms are in place."
The companies are operating under the Reform Government Surveillance coalition banner, and claim to have made a number of internal moves to shore up their users' and members' data.
The letter said that the US Freedom Act will bring privacy benefits to consumers. "Now, the Senate has the opportunity to send a strong message of change to the world and encourage other countries to adopt similar protections," it adds.
"Passing the US Freedom Act, however, does not mean our work is finished. We will continue to work with Congress, the Administration, civil liberties groups and governments around the world to advance essential reforms that we set forth in a set of principles last year."
