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.
Acton left WhatsApp late a year ago and joined in the growing backlash against Facebook, endorsing a campaign that encouraged users to delete their profiles from the social network.
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". "But it is time for me to move on".
As reported by several sources now Koum has had disagreements regarding data and encryption management, but there have been other reports of several employees who are said to have been affected morally over the data misusage of the Facebook-owned company, according to The Washington Post, these workers are planning to leave the company this November. People familiar with the matter claim that the WhatsApp co-founder had become more and more concerned about how Facebook harvests user data. That comment further tries to downplay the idea that Facebook pushed Koum away by trying to erode encryption. The WhatsApp co-founder attempted to push back where possible, but felt that Facebook's board of directors "paid lip service to privacy and security concerns he raised". Facebook bought WhatsApp in 2014 for $19 billion in cash and stock.
Why Facebook asked users if posts contained hate speech
The question showed up underneath posts and included a prompt so users could flag the item as potential hate speech. Each post also gives the option to dismiss the question with a tiny "x" box to the right of the answers.
Facebook has been the centre of a lot of attention following the Cambridge Analytica scandal where, allegedly, private data of users was sold.
Yet, circumstances of Koum's departures aren't cleared and he won't stand for re-election to the board at Facebook's May 31 annual meeting. We know that Facebook's entire business model hinges on targeted advertising around personal data.
WhatsApp's other co-founder, Brian Acton, left the company a year ago and has since tweeted support for the #DeleteFacebookMovement last month.
