It turns out even $19 billion isn't enough to convince people of the merits of Facebook.

In what will surely be arab new sex videosanother blow to Facebook, WhatsApp cofounder Brian Acton appears to have joined the growing movement to leave the social network.

In a tweet, Acton said that "it is time," adding the hashtag #deletefacebook.

He didn't elaborate, but Acton, who previously headed engineering for WhatsApp, is a well-known advocate for privacy and encryption.

The WhatsApp cofounder left the company six months ago, four years after Facebook acquired WhatsApp for $19 billion (the acquisition netted Acton as much as $3 billion from the deal). After leaving, he joined the Signal Foundation, a nonprofit organization that oversees the encrypted messaging app Signal.

He isn't the first former exec to criticize the company, but he's one of the most high profile to do so, which will no doubt be embarrassing for Facebook, which is facing numerous investigations, a tumbling stock price, and questions about its current leadership (or lack thereof).

Interestingly, it doesn't appear that Acton has taken his own advice just yet. His Facebook profile is still live.
