For those who are on the side of Apple and wants to keep iMessage on their iPhones... need to understand that allowing iMessage on Android benefits you (shocker!).
Maybe short-term, but if it creates more uptake of iMessage rather than an interoperable standard, it still increases Apple's overall power in the market. Messaging is a network effect system, so if we get a majority of US Android users are now _also_ using an iMessage-supporting app for SMS/MMS and iMessage (and it would be a ****** experience otherwise), it will be next to impossible to ever break that hold.
iMessage is designed so that Apple sets the formats allowed for messages, and all traffic goes through Apple servers, using an Apple account. Compare this to RCS, SMS, MMS, Matrix and XMPP where groups of companies have agreed on a baseline level of functionality and can all build their own servers and client software.
I have zero, ZERO concern about messaging people based on what their phone make and model is. My discrimination against android phone users starts and stops at technical support. However I'm both unqualified to do such support, and the android UX is lousy enough that I want to throw the damn phone against a wall - probably not what they want.You won't have to be concerned about "oh, they have an Android... I don't care to message them." Look at the data from teenagers and especially in the dating world. It removes that barrier. And I know you might be wondering... well, there's plenty of other messaging platforms to exchange messages with for Android users.
An official iMessage for Android would effectively kill usage of several other messaging products in the US, including likely Google's.But the issue is that most iPhone users IN THE US... gravitate toward iMessage. If we (in the states) can agree to move to a cross-platform messaging app... this whole situation would be mute.
