EPIC has filed a supplemental complaint regarding Facebook's $19 b purchase of WhatsApp. WhatsApp users had relied on the messing app's pro-privacy practices to protect their personal information, while Facebook regularly incorporates user data from the companies it acquires. In the initial complaint, EPIC urged the Federal Trade Commission to block the sale unless adequate privacy safeguard for WhatsApp user data were established. In the supplemental complaint, EPIC provided more evidence that WhatsApp users object to the acquisition. EPIC also highlighted the importance of the FTC's pre-merger review process. Recently, the Commission approved Google's purchase of Nest Labs without considering the privacy implications for consumers.
