The fork is a planned upgrade. Bitcoin Cash will continue to fork like this, at least one more time if not more to make sure that blocksize increases a long time ahead of demand. (As it used to in Bitcoin in the early days).

("BCash" is a slur introduced by a coordinated diversion campaign that also included a social media spam campaign. It's not a good name, considering the many previous forms of e-cash with similar names and the company with the same name.)
