If you've been paying attention, H.265 licensing is a disaster, even worse than H.264. It's many times more expensive, and there's ongoing issues with separate patent pools and several rightsholders refusing to join any.
Essentially everybody in the computer industry (Intel, ARM, NVidia, AMD, Google, Microsoft, Mozilla, Netflix, Cisco, Adobe, Broadcom) that isn't Apple has decided enough is enough of continual MPEG licensing issues and to go with VP9's successor AV1.
If Apple doesn't support VP9 and AV1, they won't be able to play any video, and I say that's good. Time to knock some sense into AV codec patent situation.
