> if they are not breaking the law, are they really blameworthy?
This mindset needs to die.
Yes. If you do something ostensibly immoral, it's still bad even if it's legal. It's still bad even if other people were going to do it if you didn't, anyway. It's still bad even if there's negative incentives that ultimately led to it. It's just still bad in general. If you have a reasonable decision and you choose to do a bad thing, you still chose to do it. It doesn't matter either, if a single person made this decision, or if a corporate board made this decision, or if a bunch of people in an angry mob collectively decided something.
What you can do is explain why it happened, but that doesn't mean that there is absolutely zero social responsibility to have. All that something being legal means is that it's legal. Something being legal doesn't necessarily mean it's good. Something being illegal doesn't necessarily mean it's bad.
We've conflated what we've come to expect from corporations to the standards we must hold them to. The standard that a corporation should live up to is indeed much higher and significantly more nuanced than "technically not breaking the law."
I'm not suggesting that I believe in no regulation. Regulation is clearly valuable in many cases, but I believe that it is clearly not inherently good (duh, bad regulation is everywhere) nor is it inherently the only solution to any class of problems. Believing that companies should not simply maximally exploit what is technically legal while still regulating them when they do abuse the system is possible and I'm pretty sure if we don't start thinking that way, we're even more screwed than we think we are.
Even if some corporations amass unthinkable amounts of influence and power and fundamentally escape the pressures of social responsibility through this, I still think that it's necessary to fight the learned-helplessness mindset. If absolutely nothing else, I think everyone is at least responsible for ensuring the bar doesn't drop so low as to allow this kind of thought process to remain "normal". It should always be thought of as abnormal, and as the threat to liberty and democracy that it clearly can be.
