I think Apple's top-down approach is showing here. Google is more bottom-up, which has its flaws, but it's more suited for cases like this one. I seems that unless one of Apple's higher-ups notices a problem nobody is going to do anything.

For example, Android and Google Assistant has had excellent support for Polish for more than a decade. Siri still doesn't support Polish at all, even though all of Apple's AI suppliers support Polish perfectly well...
