AND ANOTHER ONE GONE: WhatsApp CEO Jan Koum quits Facebook due to privacy intrusions.

“It is time for me to move on . . . I’m taking some time off to do things I enjoy outside of technology, such as collecting rare air-cooled Porsches, working on my cars and playing ultimate frisbee,” WhatsApp co-founder, CEO and Facebook board member Jan Koum wrote today. The announcement followed shortly after The Washington Post reported that Koum would leave due to disagreements with Facebook management about WhatsApp user data privacy and weakened encryption. Koum obscured that motive in his note that says, “I’ll still be cheering WhatsApp on – just from the outside.”

Facebook CEO Mark Zuckerberg quickly commented on Koum’s Facebook post about his departure, writing “Jan: I will miss working so closely with you. I’m grateful for everything you’ve done to help connect the world, and for everything you’ve taught me, including about encryption and its ability to take power from centralized systems and put it back in people’s hands. Those values will always be at the heart of WhatsApp.” That comment further tries to downplay the idea that Facebook pushed Koum away by trying to erode encryption.

Slightly off topic, but posting a photo to Facebook the other day made me wonder if giving Facebook permission to access my family photo library also gives Facebook permission to upload, analyze, and cross-reference my family photo library.
