If you mean you feel compelled to sell in their store which requires a laptop, a business relationship with Apple, and realistically a phone because emulator only sucks then that's a business decision if the juice is worth the squeeze.
>There's always one Android user in the friend group that spoils iMessage and FaceTime
You can't be the "everyone else is one it" social network when every Apple user uses a 3rd party messenger and video chat app for at least one person. That app ends up being the winner.
I don't even know why you're trying to debate this as the dominance of iMessage in the US is well documented as is the belittling of Android users which you yourself exemplfied in your last post. Unless by "Apple's network effect is basically zero" you just mean "I can't beleive android users still exist, they are still spoiling iMessage for me."
And a lot of apps launch early on iOS or have better features on iOS or never even launch at all on Android. Less so these days but it's still a thing. I was just in Japan and you can use an iPhone to pay for mass transit but not a non Japanese Android phone, just as one recent example.
If you feel compelled to use a product with policies you don't agree with then now you understand how many of us feel about iOS.
