Apple also relies on the path of least resistance as well, if someone is having a poor experience in a group chat with their iPhone friends...it just becomes "easy" for them to choose an iPhone the next time they change phones.
Look at other companies, Microsoft porting Office etc to MacOS, Google services like maps gmail etc available on the iPhone.
