There's many ways to measure market share and when you look at monetizable users, Apple platforms have an outsized amount of big spenders compares to Android or web platforms. As I already said, this gives them considerable influence in what does and doesn't get adopted by developers. This is the opposite of how you claim it works.

We're going to have to agree to disagree because your argument you've made twice now without adaptation is a bit absurd. If Safari doesn't implement it it must not be important? I am now conscious of my original comment being inexplicably downvoted and I'm worried I might be banging my head against Apple fanboys instead of having a discussion about corporate influence over web standards. There is considerable evidence for this and I've given it in this thread.
