I don't see much wrong with six teams choosing not to play defense for one match. It's their match, their regional, they can do whatever they want. They are still clearly trying to win the match, and that's what matters "ethically".

What this match proved to me is that this game just isn't exciting. When there is no defense, four robots are literally standing around doing nothing. At other events, these teams play defense, which makes the offensive play look worse and grittier with a few notable exceptions. Perhaps excluding matches where the best teams in the world are both playing offense and some defense, this game isn't going to be very interesting to watch in most cases.
