Facebook secretly spied on Snapchat usage to confuse advertisers, court docs say

Unsealed court documents have revealed more details about a secret Facebook project initially called "Ghostbusters," designed to sneakily access encrypted Snapchat usage data to give Facebook a leg up on its rival, just when Snapchat was experiencing rapid growth in 2016.

"Whenever someone asks a question about Snapchat, the answer is usually that because their traffic is encrypted, we have no analytics about them," Facebook CEO Mark Zuckerberg (who has since rebranded his company as Meta) wrote in a 2016 email to Javier Olivan.

"Given how quickly they're growing, it seems important to figure out a new way to get reliable analytics about them," Zuckerberg continued. "Perhaps we need to do panels or write custom software. You should figure out how to do this."

At the time, Olivan was Facebook's head of growth, but now he's Meta's chief operating officer. He responded to Zuckerberg's email saying that he would have the team from Onavo—a acquired by Facebook in 2013—look into it.
