>Abusing your ecosystem is one thing (ex. defaulting to Apple Maps for location links, only allowing Safari as default browser), but not allowing 3P app stores seems perfectly within a company's rights.

Is taxing every purchase on your platform for 30% not abusing your ecosystem?

>I think that is the issue. Android offers (nearly) all of the same functionality and yet people still choose iPhone.

iMessage is a non zero cause of this, and looking at the percentage of teens with iPhones, 85+%, likely a colossal cause. Which directly falls into Apple abusing their ecosystem.
