Why no iMessage for Android? Apple exec explains why the service is staying closed
Earlier, we rationalized that perhaps Apple saw a roundabout way that iMessage could be some kind of “hook” helping to lure Android users to iOS; clearly, that wasn't what the company ultimately had in mind.
The other reason given for not opening iMessage to Android is a little less intuitive: iMessage is already big enough. The unnamed Apple executive suggests that the iMessage user base is so large (with a billion devices in service), that it's generating more than sufficient language data for any iMessage-driven artificial intelligence learning project that Apple might want to undertake – and adding new Android users wouldn't make that data any more useful.
While those explanations might not be great to hear, especially if your group of friends extends across platforms and keeping in touch right now is a bit of a pain, it's hard to fault Apple for its logic. If there's no direct benefit to expanding access to iMessage, why do it?
