I'm just guessing... I suspect it was damage prevention, much more so than cheating. Cheating only affected the arcade owners if you were cheating on a busy machine, and somehow cheating well enough to actually extend your game. Longer games = less quarters. But, really, how many people were cheating at pinball well enough to extend their games? I think that would take some serious skill. I think most people banging the machines damaged the machines far more often than they extended their games. So I think it was mostly about that.
