Mark Zuckerberg uses WhatsApp rival messaging platform Signal

The news of Zuckerberg’s revelation of using Signal comes at a crucial time when WhatsApp’s new privacy policy is inching closer. Signal also took a dig at Zuckerberg on Twitter, saying “With the May 15th WhatsApp Terms of Service acceptance deadline fast approaching, Mark leads by example.” Apart from Zuckerberg, Facebook’s co-founders Chris Hughes and Dustin Moskovitz were also a part of the data breach.

Facebook-owned WhatsApp’s controversial new privacy policy will kick into effect from May 15th. The popular messaging platform has asked users to accept the new terms and conditions in order to continue using the app. The updated policy changes how Facebook can access user’s chats with business accounts. This has led to a worldwide outrage with many users moving to alternatives like Signal and Telegram. 

In the past, Mark Zuckerberg has pushed for end-to-end encryption on all three social media platforms that Facebook owns – Messenger, Instagram and WhatsApp.

Six million out of the 533 million Facebook users affected by the data breach are from India. According to a Bloomberg report, the database of stolen phone numbers was posted to a Hacker’s forum.
