Did you read the comment I was responding to? They said corporations don't exist and the individual humans deserve all of the blame. I fully agree with everything you said except for "No one says structure doesn't influence behavior"; I think that's pretty much exactly what the comment I responded to argued.
I don't have access to that commenter's state of mind, but I take it to mean that the "corporation" as a singular entity only exists on paper and in fact acts as a group of individual humans. I don't think that's the same thing as saying the structure having _no influence_, especially since that structure pays people and money influences the behavior of individuals. No influence is a much stronger claim than what was made. But I could also just be projecting my thoughts on the matter onto others when I say "no one says structure doesn't influence behavior".
I guess we'll just have to agree to disagree then. The context of their comment was whether the corporation or humans are to blame, and the comment I responded to reads to me like saying that the corporation has no blame and the humans have all of it.
Your opinion honestly does seem mostly aligned with mine (there's potentially blame for both the corporation and the individuals, with the corporation's portion of the blame being from influence on the individuals), and personally I find it kind of hard to determine how much the individual deserves since it depends a lot on circumstances we might never know (e.g. if the individual had a really sick family member, I genuinely might find it understandable that taking a job from Google that pays well even if it's doing some weird stuff with browsers; that's an extreme example, but my point is that I don't think whether it's blameworthy or not is a binary). I just don't read the comment I responded to as agreeing with any sort of nuance like that; my reading is that they're asserting that the individuals are fully and solely blameworthy and that the fact that they were operating under the behalf of a corporation is insignificant.
