Like when Wells Fargo investigated their mortgage department and found no problems, right? Or when Google investigated Andy Rubin and decided he wasn't that bad and protected him for three more years? Why on earth would you ever trust a corporation to police themselves? They always lie, they always fail.
It can't hurt to expect companies to actually troubleshoot their own policies. We don't have to expect that it's the only recourse (eg. government regulation, civil suits, public brand shaming, etc).
Sure it can, you’ll just end up demoralizing yourself. Expect companies NOT to troubleshoot their policies, and then when one occasionally does you’ll be pleasantly surprised. If you expect them to police themselves, most of the time you will end up being disappointed.
