The amazing thing about our society is that in most cases, the incentives of individuals are such that even bad people engage in good behavior. You say that businesses and business persons have been making destructive decisions "for decades" but there's definitely a reporting bias there; an overwhelming majority of businesses quietly ship bacon, pack boxes, deliver fertilizer, fold laundry, etc without any moral/shame oversight from senators or society at large. In fact, many of these businesses are likely ran by sonofabitches, but they still engage in good behavior because their incentives are aligned with their consumers.
The problem with Equifax and other headline news behaviors (pollution, bank crashes, etc) is not 'bad people made terrible decisions' but 'bad people had no incentive to make right decisions' because, for example, the credit bureaus are simply not motivated to protect consumer data. Legal and financial incentives are both aligned against consumers, not for them.
It's a little unfair to pile on the CEO of Equifax or the company because that's just fighting yesterday's battle too late. What we should be doing is fixing the incentive structures such that future Equifaxes don't happen.
Also, as other commenters have pointed out, we don't want to discourage good people from running credit bureaus out of fear that innocent mistakes may get them hung.
