According to this Times’ analysis, that’s not true. Or rather, people may have been saying/believing it, but they say the data does not bear it out:
When asked about the effects of the rule changes, Rob Manfred, the commissioner of Major League Baseball, focused on the positive effects it has had on the game’s offense. “Enforcing our rules is really important — they’re on the books, they should be enforced,” he said, calling the changes in play “very promising.” He was particularly pleased there had been no increases in batters hit by pitches — a point that he has made before and that has been backed by data showing batters have been less safe in this recent era of sticky substances.
