Yep, I already pay for iCloud, Applecare on several devices and yet I am still punished by Apple via iMessage for using Android as my main device. (I also own a newish iPhone but even that's not good enough without workarounds to use my primary phone number with iMessage).
I don't like the idea of ever being bound to a single ecosystem and Apple's lack of interoperability by design keeps me using many Google services because they offer almost everything for both iOS and Android.
I would imagine a significant number of people would be willing to spend $5-$10/mo to be able to use iMessage + FaceTime as native Android/Windows apps (you can already FaceTime with non-Apple users via a link [0])
