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.

The documents were filed in a class-action lawsuit from consumers and advertisers, accusing Meta of anticompetitive behavior that blocks rivals from competing in the social media ads market.

"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.
