“Bitcoin cash” is a name chosen to confuse newcomers and attempt to steal the bitcoin brand. The CEO of bcash refers to Bitcoin as “SegwitCoin” and their official /r/btc subreddit regularly claims to be the real bitcoin.
Bcash is an appropriate name for the altcoin to eliminate confusion.
Note that there is no CEO and the very same people who refer to Bitcoin Cash as Bcash refer to Ethereum Classic, Bitcoin Gold and others by their proper name...
