“Everybody who wants to join 'WhatsApp', we'll go out of our way to build a really awesome client for them.”
“WhatsApp's extremely high user engagement and rapid growth are driven by the simple, powerful and instantaneous messaging capabilities we provide.”
“No one wakes up excited to see more advertising, no one goes to sleep thinking about the ads they'll see tomorrow.”
