The Federal Trade Commission (FTC) has locked horns with tech goliath Facebook again over allegations that it monopolizes the personal social networking (PSN) services market. Wednesday's opposition to Facebook's motion to dismiss contends that the FTC's amended complaint (AC) builds on allegations about the PSN services market and bolsters its contentions with new indirect and direct evidence of the company's monopoly power. Last month, Facebook pressed the District of Columbia court to dismiss the complaint once again, contending that the FTC's refreshed arguments do not make the lawsuit seeking the divestiture of assets like Instagram LLC and WhatsApp Inc. any more viable. The company also argued that the vote to file the amended complaint was tainted by the publicly demonstrated bias of FTC Chairwoman Lina Khan.
