Despite everyone wanting them to fail, this is inaccurate. They’ve sold as much Quest hardware as Microsoft sells Xboxes in the same time period, and those cost figures include hardware, and ALL their VR software, across multiple different games and apps. They did not spend that much on Horizon Worlds which is their failed second life clone.
Neither Microsoft or Facebook are making relevant money from hardware. All of those headsets (like all those xboxes) have only one purpose: selling software, which the platform owner takes a cut from.
Incidentally: from 2021 to 2022 reality labs both sold less hardware and less software, while growing their costs, probably due to research and development and preproduction for both Quest Pro - which is cancelled already - and Quest 3. Let’s wait and see, what Quest 3 is getting Facebook, but currently reality labs is failing, no matter how much I personally want them to, as well.
