Judge James Boasberg largely denied Meta s motion to end the case filed against Facebook in 2020, during the Trump administration, alleging that the company acted illegally to maintain its social network monopoly.

Meta, then known as Facebook, overpaid for Instagram in 2012 and WhatsApp in 2014 to eliminate nascent threats instead of competing on its own in the mobile ecosystem, the FTC claims.

Boasberg let that claim stand, but dismissed the FTC s allegation that Facebook bolstered its dominance by restricting third-party app developers  access to the platform unless they agreed not to compete with its core services.

"We are confident that the evidence at trial will show that the acquisitions of Instagram and WhatsApp have been good for competition and consumers," a Meta spokesperson said on Wednesday.

FTC spokesperson Douglas Farrar said that the case filed during the Trump administration and refined under Biden "represents a bipartisan effort to curtail Meta’s monopoly power and restore competition to ensure freedom and innovation in the social media ecosystem."

At trial, Meta will not be allowed to argue the WhatsApp acquisition boosted competition by strengthening its position against Apple (AAPL) and Google, Boasberg ruled.

The judge said he would release a detailed order later on Wednesday after the FTC and Meta have had a chance to redact any sensitive commercial information.

A trial date in the case has not been set.
