i am unsure what you mean about not interfaceing with apple? I heard in america imessage is a big thing that prevents that, but the rest of the world doesnt really use it. and besides there are many messangers that let you interface.
also i mean the burden to move. the burdon to leave the alphabet system is just as hard as the apple system imo. its just annoying both dont make it easy for any cross useage.
Edit: just wanna make clear i am not an apple apologist. i heavily prefer open source alternatives and use them whereever i can. i just dont get how people act as if andeoid/google/ect. are better or even good alternatives.
as a hige indi/small developer fan i see great times ahad. AAA will fail, clmpanys will close and developers will find new homes in smaller teams. by 2030 i predict a golden age for AA and and perhabs also a new golden age for indi.
