You're looking at it from iOS side only, and for a US company that would be the last platform they'd ever drop.

It was a different picture out of the Apple garden, when a company only brings their next major feature to iOS because they couldn't be bothered to hire the same headcount on two development teams and their CEO uses an iPhone anyway.

We had that discussion about a decade ago with a company rep that didn't realize 70% of their EU users were on Android yet their play store app didn't have the feature they were planning to promote.

Basically, better was the enemy of good for most companies.
