Ok. In MLB teams and players in an organized way and unorganized have been stealing signs for as long as there have been signs. They aren't taking down the records of the steriod era or the batting numbers of players found to be corking their bats and pitchers found to be using illegal substances. Cheating isn't new. I cant change your mind on this and will move along. MLB did dodge a missile when the Nats beat them this last WS.
There's a big difference between two teams using their wits to steal or guard signs vs one team using technology via home field spy equipment. In one case both teams can try to steal or manually guard against stealing. In the latter case there is a clear, asymmetrical advantage and no way for the other team to know or counter.
The steroid debate is vast and players have suffered consequences when caught. It's hard to quantify a win or loss based on steroid use, compared to an organization that can be shown to have used tech to tilt the game in their favor in ways the other team could not.
Some managers don't want to steal signs at all. Mine didn't.
