Who said that we do have to? - certainly not me. As I've said, whether it is considered "right, desirable or inevitable" is a matter of (personal, national, cultural, academic etc.) opinion. The point I made in the sentence following the one you quoted was that evolution of language was, in fact, much the same before the new communication technologies came into being.Just because new technology facilitates something new that doesn't mean we have to accept it as right, or desirable, or inevitable.
