Cheating in baseball (and all pro sports, TBH) is nothing new. Teams have been cheating by steal signs (Astros, Yankees, Red Sox (x2) confirmed, dozens of others rumored), throwing spitballs/scuff balls, PEDs in the 90s, amphetamine in the 60s, cocaine in the 80s, manipulation of the humidors, etc. The list of cheating confirmed in baseball is huge, and the alleged cheating is almost endless. Whenever you have ultra-competitive humans going after fame and fortune, "bending" the rules to get an edge is the most likely outcome.
The difference for the Astros was twofold--first, they had a rat that went on record with the details to the Athletic, years after the event. Second, the method of cheating was easily "verifiable" by the average idiot with access to youtube. The Red Sox and Yankees cheated, but the system was more complicated than the audible trash can bang.
I also find it funny that we draw a line at what is "cheating". If I steal signs as a baserunner and relay them to the batter, almost universally that is considered gamesmanship. If, as a baserunner, I get info from the dugout and relay it to the batter, that is "cheating".
