‘Barron’s Roundtable’ discusses the value hidden in Facebook’s diverse revenue streams.
A hack of millions of Facebook users’ data has revealed that the company’s CEO Mark Zuckerberg uses the secure messaging app Signal, one of the main competitors of the Facebook-owned WhatsApp.
Dave Walker, a cybersecurity researcher, discovered that Zuckerberg was among more than 533 million Facebook users whose information was leaked in the 2019 hack, Mashable reported.
“In another turn of events, Mark Zuckerberg also respects his own privacy, by using a chat app that has end-to-end encryption and isn’t owned by @facebook,” Walker tweeted, along with a photo of Zuckerberg’s redacted phone number, which he linked to a Signal account.

Signal, one of WhatsApp’s main competitors, is an encrypted messaging app, meaning that the company cannot access any messages or calls made by users on the app.
After the news broke of Zuckerberg’s supposed use of Signal, the company retweeted a link to the story writing: “With the May 15th WhatsApp Terms of Service acceptance deadline fast approaching, Mark leads by example.”
