The "standards" Apple is currently refusing to implement are already standards in name only: They're Google written specs solely implemented on Google's browser which generally is only also adopted by rebranded clones of Google's browser. Mozilla has also refused most of them, but since Mozilla doesn't also have an operating system, Google happily sidesteps them.
