Well not if users force VP9 using something like youtube-dl and pipe to a compatible player. But I looked it up and the reason Apple refuses to adopt VP9 is not so arbitrary but rather because they're part of MPEG LA, with HEVC being the competitor to VP9. It's unfortunate that there's so much fragmentation with standards simply because of corporate interests.

It is unfortunate but it’s been happening forever.

And yet, things continue to work and continue to progress for the most part, so format wars aren’t necessarily as big a problem as we like to think.
