Yep, I think PT is absolutely right with what he's doing here, raise it, make it very clear why this would be unacceptable and then leave it with the club to decide how they proceed. If they go ahead then clearly the financial rewards are worth the potential loss of goodwill, etc but the time to complain is before anything has happened not by boycotting the shirt when it's already too late for the club to back out until next summer.
