The Federal Trade Commission on Thursday took a second shot at alleging Facebook is an illegal monopoly in a new complaint that accuses the social media company of buying up potential competitors or thwarting their access to the platform.

Why it matters: The FTC, now led by Big Tech critic Lina Khan, is trying to save its case against Facebook after a judge dismissed its first attempt.

Driving the news: The FTC filed an amended complaint in a D.C. federal court arguing Facebook illegally acquired competitors WhatsApp and Instagram, and that Facebook "lured" app developers to its platform and "buried" them when they became competitive threats.

• In June, Judge James Boasberg dismissed the agency's first complaint, noting that it lacked specifics on the metrics or methods used in defining and calculating Facebook's market share, but allowed the agency to try again.
• The FTC said in a press release that its new complaint bolsters its arguments with new detailed statistics on Facebook's market share and new evidence showing Facebook has the power to control prices or exclude competition.

What they're saying: “Facebook lacked the business acumen and technical talent to survive the transition to mobile," said Holly Vedova, FTC Bureau of Competition Acting Director.

• "After failing to compete with new innovators, Facebook illegally bought or buried them when their popularity became an existential threat. This conduct is no less anticompetitive than if Facebook had bribed emerging app competitors not to compete."

The other side: Facebook has previously argued that the government's case ignores the competition that the company faces from companies like Apple, Google, Twitter, Snap, Amazon, TikTok and Microsoft.

• Facebook did not immediately comment on the new complaint from the FTC.

The intrigue: Facebook called on Khan to recuse herself from the case, given her previous work on antitrust issues for the House Judiciary Committee and her public criticism of the company.

• The FTC says the Office of General Counsel reviewed the Facebook petition and Office of the Secretary dismissed it, noting that the case will be prosecuted before a federal judge

Flashback: The FTC filed the case in the waning days of the Trump administration, with then-Chairman Joe Simons, a Republican, joining with the agency's two Democrats to bring the complaint over the objections of the two Republican commissioners.

• The Democratic and Republican leaders of the House and Senate antitrust subcommittees urged Khan to continue enforcement efforts against Facebook for potential antitrust violations in a letter following the judge's dismissal of the complaint.
