On the heels of a U.S. House of Representatives subcommittee report, a new class action alleges that Facebook used “copy, acquire, kill” methods to wipe out its competitors and illegally monopolize both the social media and social network markets.

The lawsuit, filed on Thursday in U.S. District Court for the Northern District of California, claims Facebook’s model of obtaining information from its users and selling them to third parties, such as advertisers and app developers, has made it difficult for competitors to create their own networks.  For those that have managed to build a substantial user base, such as WhatsApp and Instagram, Facebook has cut them off or purchased them for billions of dollars to eliminate the competition.
