He's even stuck to his values, remaining adamant that the acquisition by Facebook wouldn't result in a change of company principles. Here's a look at the reactions to Koum's exit and what has been confirmed so far. Mr. Koum is up for reelection as a Facebook director, according to Facebook's proxy filing earlier this month.
Facebook CEO Mark Zuckerberg posted on Koum's timeline, writing he was thankful for what Koum taught him about "about encryption and its ability to take power from centralized systems and put it back in people's hands". As previously reported, the company is now moving towards paid-for business messaging accounts.
Concerns about Facebook's handling of personal information have grown since the social network's admission in March that the data of millions of users was wrongly harvested by political consultancy Cambridge Analytica.
Mr Jan Koun, 42, one of the founders of messaging app "Whatsapp", has made a decision to leave Facebook.
The departure comes almost four years after Facebook (FB) completed its acquisition of the messaging service for $22 billion, the largest purchase in its history. Koum has announced that he will soon be leaving the popular messaging platform.
Koum and Acton, both former Yahoo employees, launched WhatsApp in 2009.
Koum and Acton were openly disparaging of the targeted advertising model. They described online advertising as "a disruption to aesthetics, an insult to your intelligence, and the interruption of your train of thought". Neither Koum nor Facebook could be reached by press time.
The House chaplain had a prayer and then he didn't
A senior Democratic leadership aide told Shareblue Media Conroy was "pushed out because he was praying for justice and fairness". Meanwhile, Conroy's last day as chaplain is not until May 24, so he is still leading the House in a daily opening prayer.
"You can still count on absolutely no ads interrupting your communication".
To recall, Facebook is now facing its toughest time with user data privacy after Cambridge Analytica. There's no confirmation on who will be the next CEO of WhatsApp. If a government or company asked WhatsApp to turn over your messages, the company wouldn't be able to, since it cannot read them.
However, their relationship with Facebook has soured recently, according to reports.
WhatsApp's top brass has been staunchly against in-app adverts for some time, so it would be surprising to hear it clashing with Facebook which loves serving up data-driven ads.
Conflicts soon arose over how WhatsApp would make money.
Instead, WhatsApp charged a $1 annual subscription.
