Facebook boss Mark Zuckerberg has said he believes secure, private messaging services will become more popular than open platforms.
In a blog, Mr Zuckerberg outlined his vision to transform Facebook into a “privacy-focused platform.”
Facebook owns Messenger and Whatsapp, but message encryption limits its ability to make money through targeted adverts.
The social media giant has come under fire for a series of privacy scandals.
In 2018, it emerged that the data of about 50 million users had been harvested and passed on to a political consultancy.
