My money is on Meta. Unity powers the vast majority of VR games and is (was) the favored API for Meta's dev tools, and even Apple chose it as their only officially supported 3rd party toolkit for the Vision Pro.
Meta seems to enjoy throwing money into the VR space to subsidize it at the low-cost end, I could easily see them doing a hostile takeover of Unity "for the good of the VR space"
Apple “chose” it might be a bit misleading. While I’m sure they could’ve gone with Unreal, the outstanding lawsuits alongside the very loud negative press from Epic made it a non starter. Outside of Unreal and Unity, there aren’t a lot of options.
