This right here is the attitude that most people have, because it's not convenient for them. Suck it up, there are many things in life you do not want to do, but you have to do them anyways.
I most definitely do not need to get a specific app to talk to people. If they require that, I simply won't communicate with them. It's pretty easy really.
This is the attitude we're trying to break. If apple won't fix it, I'll find an alternative means of communication. If that requires downloading an app, so be it, it's not gonna hurt you.
