That is not a problem with A/B testing. It's a problem with the values of the company. I've worked with people who will say, "Oh, this tests well, but we don't want to do it because of [long term concerns X and Y]."
People who value revenue metrics over all else will still do shitty things for users even if they don't A/B test.
