I'll take Tim at his word on this. If Apple iOS/iPhone users wanted RCS as a default over SMS. Then ask for it. Petition Apple for the feature, request it like any other feature we would like to see on the iPhone.
No guarantee it will happen, but like everything else. If you don't ask for it, don't expect to get it. iMessage works great for me. And I enjoy the innovations that have come to it over the years. As it generally gets "used" almost immediately after it's made available. And, tends to work well right off the bat.
I for one don't really care if RCS became the next standard or not. I'm not all bent out of shape seeing a green bubble vs a blue bubble. I understand some are, but as long as the message comes through is all I really care about.
Most of my community of friends/co-workers/family. All have iPhones. With maybe 5 or so of them having an Android phone. It simply doesn't affect me as it may other people. It's annoying when you get a picture or video that's not properly formatted from an Android or iOS to the other. But, again for me it's not a big enough problem.
Hence why Tim maybe saying what he did. Our users aren't asking for it. Many iOS users most likely are in the majority that simply don't care about this issue. Is Apple going to get more users to iOS with this feature? Or, do they like iMessages enough as is to stick with the product?
As far as the other "innovations" go that Google claims they did first. iOS was first. Google moved into that direction shortly after seeing it.
And it was hideous. It was a better Blackberry than a better iPhone. But Blackberry wasn't the future.
Pixel has innovative features, and plenty of handset manufactures have made innovative improvements with hardware and software. It's just really easy for them to say "we like it when others copy our innovations". When they copied themselves. Apple didn't copy Blackberry. They went their own way. Google copied or tried to improve on Blackberry, but ended up copying Apple. They made improvements and added features as well. All can be true.
