Uncovering and explaining how our digital world is changing — and changing us.

Fight for the Future, the group behind the protests outside the FBI headquarters and Apple stores last month, is planning another show of support for Apple’s fight to preserve encryption.

The group is launching an online campaign, SaveSecurity.org, to collect comments and signatures from Internet users opposed to government back doors. The comments will be read aloud outside the U.S. District Courthouse in Riverside, Calif., on March 22.

That’s the day Apple and the government will argue in federal court over whether to throw out a judge’s order that the company help investigators hack a phone used by one of the San Bernardino attackers.

“This case is not just about one phone, it’s about the future of safety and security for millions of people all over the world,” said Evan Greer, campaign director of Fight for the Future. “We’ll be outside the courthouse to make sure those people’s voices are heard.”

This is the same group that organized some pretty significant online protests, including the SOPA blackout against online censorship.
