On Thursday, Biden administration accused Meta Platforms of trying to buy its way to dominance in the metaverse.
This was to block Facebook's parent company from buying the virtual reality app Within Inc.
The FTC filed a lawsuit in July to block the deal, saying Meta's acquisition of Within tends to create a monopoly in the virtual reality fitness app market.
It asked a judge to issue an injunction to stop the proposed transaction.
FTC Attorney Abby Dennis said that Within acquisition was intended to attract a new and more diverse set of virtual reality users.
Dennis added, this will complement Meta's existing virtual reality audience, who tend to be younger and more gaming-focused.
Lawyers for Meta and Within argued that companies were competing with a wide variety of fitness content, not just VR-specific fitness apps.
