Following Facebook's announced plan to purchase WhatsApp, a popular pro-privacy messaging services, EPIC urged the FTC to block the acquisition. EPIC explained to the Commission that Facebook incorporates user data from companies it acquires, and that WhatsApp users objected to the acquisition. WhatsApp founder Jan Koum has now published a blog post in response to the EPIC Complaint. Koum wrote, "Above all else, I want to make sure you understand how deeply I value the principle of private communication. For me, this is very personal." He added, "Make no mistake: our future partnership with Facebook will not compromise the vision that brought us to this point."
