I think moving away from the term Ethereum is a move in the wrong direction. Ethereum Classic needs to take ownership of the word Ethereum and thus should be doing everything possible to show the world that it is the true Ethereum while the other is just a fork that should have a different name. On a marketing level why start a new brand when you already have substantial control over an already established brand name that many in (and outside) the space know and respect? Ethereum Classic is Ethereum not Expanse.
