As for WhatsApp, Facebook CEO Mark Zuckerberg noted that people have already used some 2 billion minutes of one-on-one video calling on the messaging service, so it's set to roll out group video chats in the coming months.
Facebook-owned popular instant messaging app WhatsApp rolled out the voice call feature to its users back in 2015.
Mark Zuckerberg's recently said on the F8 keynote speech that Jan Koum was a "tireless advocate for privacy and encryption" and thanked him for helping turn Facebook into the "largest fully encrypted communication network in the world".
"It is time for me to move on".
The CEO and co-founder of WhatsApp, Jan Koum, has chose to leave parent company Facebook as he was apparently unhappy with privacy decisions being made by the social media empire. The social networking company, Facebook declined to comment on Koum's departure date. "Those values will always be at the heart of WhatsApp". Granted the founders, who gleaned $19 billion from the sale of the app, probably aren't losing too much sleep over Facebook's policies. And I'll still be cheering WhatsApp on - just from the outside.
Facebook has taken steps to generate revenue from WhatsApp, which unlike Facebook does not have advertising.
Jan Koum has been recently growing a lot of concern on Facebook's focus on collecting and selling user data.
A year and a half later, though, Facebook pressured WhatsApp to change its terms of service and give users' phone numbers to its parent company. Facebook was eventually fined $122 million by the European Union in 2017 - a paltry sum for a company earning more than $4 billion in profit per quarter. Alongside some key announcements related to Facebook and Instagram, the social media giant announced two new massive features which are coming to WhatsApp.
WhatsApp's other co-founder, Brian Acton, left the company past year and has since tweeted support for the #DeleteFacebookMovement last month.
