Amazon Defends Its Use of Signal Messages in Court

America's Federal Trade Commission and 17 states filed an antitrust suit against Amazon in September. This week Amazon responded in court about its usage of Signal's "disappearing messages" feature. Long-time Slashdot reader theodp shares GeekWire's report:At a company known for putting its most important ideas and strategies into comprehensive six-page memos, quick messages between executives aren't the place for meaningful business discussions. That's one of the points made by Amazon in its response Monday to the Federal Trade Commission's allegations about executives' use of the Signal encrypted communications app, known for its "disappearing messages" feature. "For these individuals, just like other short-form messaging, Signal was not a means to send 'structured, narrative text'; it was a way to get someone's attention or have quick exchanges on sensitive topics like public relations or human resources," the company says as part of its response, filed Monday in U.S. District Court in Seattle.Of course, for regulators investigating the company's business practices, these offhanded private comments between Amazon executives could be more revealing than carefully crafted memos meant for wider internal distribution. But in its filing this week, Amazon says there is no evidence that relevant messages have been lost, or that Signal was used to conceal communications that would have been responsive to the FTC's discovery requests. The company says "the equally logical explanation - made more compelling by the available evidence - is that such messages never existed." In an April 25 motion, the FTC argued that the absence of Signal messages from Amazon discussing substantive business issues relevant to the case was a strong indication that such messages had disappeared. "Amazon executives deleted many Signal messages during Plaintiffs' pre-Complaint investigation, and Amazon did not instruct its employees to preserve Signal messages until over fifteen months after Amazon knew that Plaintiffs' investigation was underway," the FTC wrote in its motion. "It is highly likely that relevant information has been destroyed as a result of Amazon's actions and inactions...." Amazon's filing quotes the company's founder, Jeff Bezos, saying in a deposition in the case that "[t]o discuss anything in text messaging or Signal messaging or anything like that of any substance would be akin to business malpractice. It's just too short of a messaging format...." The company's filing traces the initial use of Signal by executives back to the suspected hacking of Bezos' phone in 2018, which prompted the Amazon founder to seek ways to send messages more securely.
