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.
I'm sure there have been a few instances, somewhere, there must be, right? I just don't recall reading or hearing about them in my entire life, ever.
