Interesting. Didn't know that. I know that the limitation still exists for Apple's ARM chips, but that shouldn't be here nor there. Apple is dropping all native support for VP9 with the current OS update, as it relied the now deprecated 32-bit functionality of QuickTime and is not supported by Apple's current AVFoundation (anything that uses FFMpeg or other codec library, like VLC, will still function). I'm sure there are a lot of details that I'm not privy to as far as licensing and royalties (or lack thereof), but I guess the reasoning now likely lies with that.
