For some market it is. Our users were 80%+ on ios

Seems to me the biggest hurdle to moving/finding customers via the Google/Android platform is that they won't spend money over there.

The feature/capability parity between the platforms means they are, in fact, both capable of serving these markets. But people want to vote with their dollars in the iOS ecosystem, and now the players want to change that ecosystem.

I'm not entirely convinced that this is Apple's problem, in as much as it is Google's fault for not fostering a properly competitive revenue delivery platform, even though it has the maturity and standing to do so.

But does that matter when they have milions of people in that marked. Isn't that a size where it really shouldn't matter anymore if there is another similar bigger marked?

Also for some serivces iOs users are the large majority, like more or less any "real premium" service (Like apps you have to pay 10 or so+$ a month or 100+$ when buying them).

It's handled case-by-case, that's the point of the legislative oversight system.
