I’m not a fan of the “war” between Android and Apple when it comes to SMS/texting. The rest of the world doesn’t use SMS/RCS/iMessage as much as WhatsApp and the like, so the US is pretty much lagging behind everyone else on this anyway.
That being said, I have to admit Android did a good job with this!
SMSes use a standard available to any app. WhatsApp is controlled by a single company.
If you were arguing that XMPP or something like that should be used instead of SMS, okay, that’s one thing, but I have a hard time favoring a walled garden.
