I think it is silly to make a big triumphant deal about it. But I also think it is funny when someone gets upset about stealing signs. If you don't expect that the otehr team will steal your signs, then why do we use signs, and attempt to hide them. Heck, even NFL coaches hide their lip movements behind their play charts because they it is part of the game to have someone with binoculars or a video feed locked onto their facial expressions ... for info. It is a game, and it si funny to see people get worked up over it in either direction.
Two years ago in 10u we ran into a similar situation. Pitcher with above average fastball, made better by a devestating change which she threw for strikes 50% plus, had her dad on the bucket. Opposing coach stole the signs and yelled to the hitter before the pitch, completely distracting the hitter. So, now everybody's upset and nothing was accomplished anyways except taking away whatever chance the hitter had to focus. Switching up simple signs would seem to make the whole concept backfire anyways, let them think they have it figured out when they don't, plus, active thinking instead of focused reaction probably favors the pitcher anyways, if she has a decent heater.
Pretty funny to me, although I know that in the Major Leagues stealing signs will get you a high tailing fastball between the shoulder blades next time up - so I guess it's just me that thinks it is no big deal.
