It's part of the game, as is beaning batters to fix it. The Baseball Codes is a remarkably good book about it all. I'm not a baseball guy but I think the white sox were caught back in the day with a groundskeeper in the scoreboard with binoculars flashing a light to indicate the pitch. I'm lead to believe there are more dimensions than just pitch speed, which is a gigantic aid. Most pitchers only have a couple pitches and placement is big too, you can put a fastball inside to back the hitter off and then have a better outside strike zone. Possibly combined with the catcher talking some trash to the hitter. It's an emotional game
