The Boston announcers had the opposite tone. They repeatedly talked about how it was the Brewers' aggressiveness that resulted in success. Even by that point the Brewers were around 25th in MLB in walks. They are currently 27th in walks and last in the NL. Then again, last year the Brewers finished dead last (30th in MLB) in walks. So I admit that maybe it isn't a new coaching decision. Obviously I don't have any proof, but it can't be a coincidence that every hitter in the lineup has been swinging away at 0-0, 0-1, and 1-0 counts. It's easy for the coaches to tell the hitters to take pitches on those counts--which obviously isn't happening.
