I think Google was in a different position than Apple in the case of messaging client. Apple has total control of the text message app on the iPhone, or Google does not. Google had to appease Samsung and likely some other cell phone makers to allow them to make their own RCS compatible app. Google took RCS and created universal profiles, and I think wants to get Apple on board with it so that there is a shared protocol between vendors. Apple went to full proprietary stack that no one else can use, while Google went the more open protocol. Open protocols like this always tend to have a bit more headache, and we're seeing that with RCS. Especially when some of the players are cell service providers. If the EU open protocol legislation ever pans out, I wonder how that would impact iMessage and RCS.
