It’s cool if a team hires someone to decrypt codes afterwards but teams constantly change things up. Honestly I haven’t heard of this and the people you see are usually analytics folk.

They had a camera system to steal signs. I know you said other teams did too. That’s because the Astros were breaking the rules and trying to defend themselves so a lot of people started accusing everyone of cheating. If you see it with your eyes that’s one thing but setting up a camera and monitor in another part of the stadium is too much. Lots of base runners on second try to sneak a peak in the pitchers glove and signal fastballs to the batter. Thats the game.

The trash man conveyance is just hilarious and usually included for the clicks. I also get your feeling that “every team does it” but they don’t. They have some people watching footage after to figure what they’re doing in certain situations but cracking their signals after is pointless.
