Why Signal Refuses to Give Government Backdoor Access to Americans’ Encrypted Communications

​Signal is an instant messenger app operated by a non-profit to enable private conversations between users protected by end-to-end encryption. Governments hate that. From Australia, to Canada, to the EU, to the United States, democratic governments are exerting ever-greater pressure on companies like Telegram and Signal to give them backdoor entry into the private communications of their users.
 
So far, these instant messaging companies don’t have access to users’ messages, chat lists, groups, contacts, stickers, profile names or avatars. If served with a probable cause warrant, these tech companies couldn’t respond if they wanted to. The Department of Justice under both Republican and Democratic administrations continue to press for backdoors to breach the privacy of these communications, citing the threat of terrorism and human trafficking as the reason.
 
What could be wrong with that?
 
In 2020, Martin Kaste of NPR told listeners that “as most computer scientists will tell you, when you build a secret way into an encrypted system for the good guys, it ends up getting hacked by the bad guys.” Kaste’s statement turned out to be prescient.
 
AT&T, Verizon and other communications carriers complied with U.S. government requests and placed backdoors on their services. As a result, a Chinese hacking group with the moniker Salt Typhoon found a way to exploit these points of entry into America’s broadband networks. In September, U.S. intelligence revealed that China gained access through these backdoors to enact surveillance on American internet traffic and data of millions of Americans and U.S. businesses of all sizes. The consequences of this attack are still being evaluated, but they are already regarded as among of the most catastrophic breaches in U.S. history.
 
There are more than just purely practical reasons for supporting encryption. Meredith Whittaker, president of Signal, delves into the deeper philosophical issues of what society would be like if there were no private communications at all in a talk with Robert Safian, former editor-in-chief of Fast Company.
 
“For hundreds of thousands of years of human history, the norm for communicating with each other, with the people we loved, with the people we dealt with, with our world, was privacy,” Whittaker told Safian in a podcast. “We walk down the street, we’re having a conversation. We don’t assume that’s going into some database owned by a company in Mountain View.”
 
Today, moreover, the company in Mountain View transfers the data to a data broker, who then sells it – including your search history, communications and other private information – to about a dozen federal agencies that can hold and access your information without a warrant.
 
When it comes to our expectations of privacy, we are like the proverbial frogs being boiled by degrees. Whittaker says that this is a “trend that really has crept up in the last 20, 30 years without, I believe, clear social consent that a handful of private companies somehow have access to more intimate data and dossiers about all of us than has ever existed in human history.”

Whittaker says that Signal is “rebuilding the stack to show” that the internet doesn’t have to operate this way. She concludes we don’t have to “demonize private activity while valorizing centralized surveillance in a way that’s often not critical.”
 
We’re glad that a few stalwart tech companies, from Apple and its iPhone to Signal, refuse to cave on encryption. And we hope there are more, not fewer, such companies in the near future that refuse to expose their customers to hackers and government snooping.
 
“We don’t want to be a single pine tree in the desert,” Whittaker says, adding she wants to “rewild that desert so a lot of pine trees can grow.”
