Meta is delaying adding end-to-end encryption to messages on Messenger and Instagram until 2023.
The current plan is about a year later than originally announced. Meta said the delay will give them more time "to get this right" and attributed the delays to concerns about user safety and the need to assist with public safety efforts, including child abuse investigations. Personal messages on WhatsApp are already end-to-end encrypted and they're working on making it the default across all of their apps. They already have encrypted voice and video calls on Messenger.
