> They've purposefully underinvested in Safari to force developers to create native apps for their platforms where Apple makes a sizeable cut

Can't speak to how accurate this is, but for WebXR, this hits the nail on the head. Purposeful stagnation on supporting it and thus indirectly bringing down the whole point of the standard, pushing of their own AppStore bound ARKit, and when they released Apple Vision Pro it's magically supported again, because I guess they needed content that badly.
