This is a big deal (albeit would be tied up in court for awhile). Getting ahead of the already planned integration of messaging across Facebook, WhatsApp and Instagram so its not a nightmare later (and it would be).

The Federal Trade Commission is considering seeking a preliminary injunction against Facebook to prevent the social network from integrating several of its messaging services, according to three people with knowledge of the matter. The agency has discussed how the Silicon Valley company is stitching together the technical infrastructure underlying WhatsApp, Instagram and Facebook Messenger, said the people, who spoke on the condition of anonymity because the talks are confidential. The F.T.C. is weighing whether such an integration would make it harder to potentially break up Facebook, they said, especially if the agency determines that the company’s acquisitions of some of those apps reduced competition in social networking. The agency has not made a final decision about what to do, the people said.
