Things rarely change because most (all?) founders and CEOs truly believe they're doing good. Whether it's just attachment to their vision despite it being an overall loss for society, or doing the math and concluding there's marginally more good than bad, or maybe just justifying a small "bad" as a price for the big "good". They are never the ones paying the price for that bad so that won't disturb their world view.
That's one common trait I discovered in almost every successful CEO or founder, the capability to brush aside any criticism in their pursuit of their vision, as long as the price highlighted by that criticism fell on shoulders outside of the company.
