Everyone abandons Khronos IP, or doesn't really supports it, paging through history in general. Because Khronos IP ends up a designed-by-committee crapfest. Meanwhile WebGPU is not and has never been a Khronos IP. It's developed within a w3c working group: https://www.w3.org/2020/gpu/

Based on a 4-year porting of what from MacOS Safari top iOS Safari?
- WebGPU spec is literally in draft status, so things can still change. It's literally in stage 2 of 5 of spec development
- Neither Safari nor Firefox have enabled WebGPU yet. The fact that Chrome rushed and enabled it by default does not make the spec or the standard finished and ready to be enabled everywhere
- webgpu can be enabled with a toggle in advanced settings in Safari on iOS (as is the case with most new features for in all browsers)
Apple is the original author of a lot of tech they end up abandoning. Certainly a lot of Khronos IP, paging through their history.
> And your fantasy of Apple deliberately avoiding it is based on what exactly?
Based on a 4 year (!!!) porting time from MacOS Safari to iOS Safari. Basically textbook feet-dragging there.
