While I think the casinos (and sportsbooks) have gone too far in trying to restrict the ways in which we can use bonuses in a way to skew the scale even more in their favour, this definitely isn't a case of them trying to pull one over on you. Terms are clearly laid out.
Based on your play and story I am almost certain this isn't the first case of you trying to maximize your EV from a casino bonus. That isn't "wrong" - you're allowed to try to profit off of promotions, however you then can't cry foul when you don't read all the rules and miss something as important as this.
