Apple

As I understand it, there was a deal between Meta and Elijia to specifically promote the App at Meta Connect, Meta called it off after hearing they were in talks with Pico & Apple.

Sounds to me like this might be purely about the additional promotion (and apparently additional payments), not about banning the App in general. But that‘s somewhat unclear to me.

Meta canceled his AEI Fitness app days before its unveiling at Meta Connect, the world’s biggest VR conference, Elijah says. He says the conference would have propelled it to the top of the VR fitness app market, eventually reaping him tens of millions of dollars. […] But while preparing to be part of Chief Executive Officer Mark Zuckerberg’s keynote, he says, he was told, “‘No, the project’s killed, we’re not giving you your money.’”

There will definitely be games and apps available on both platforms, some have already been announced (Rec Room, Demeo).
