It's a reminder of the rule that you're not allowed to compare games in your reviews (because some have review-bombed games in the past). Games in a school setting often get compared to Being a DIK so they put a reminder on those games. So it's not just this game, it's also on A.O.A. Academy and other games where people keep making comparisons to Being a DIK. Being a DIK has some militant fans who feel a need to attack any game that resembles it in any way, but thankfully, it has been less of a problem latley.
