That’s certainly less desirable option for many. But why is wanting modern cross platform messaging so bad? It works iPhone to iPhone, works Android to Android, theoretically if there were other players (maybe if BB or Windows still had phones) they could also achieve the same using RCS with Android. This argument is and has always been about default protocols that phone can communicate with. Of course downloading 3rd party chat apps, emailing them, mailing them a letter, using a cup and string, stopping communication because they chose to use a phone from a different manufacture are all still “options”.
