No it’s not. I use an iPhone. When I message people with an Android phone, my experience is worsened. Apple isn’t going to let Android anywhere near iMessage, so Google is instead suggesting RCS as the alternative that will improve inter platform messaging. Apple, however, would apparently prefer that I become an iPhone salesman instead of work on a solution for their own damn customers.
It doesn’t even have to be RCS, Apple could work with Google on an entirely different standard that’s up to their standard. But no, they want the experience to be bad because they want me to pressure friends and strangers to buy their phone.
