I think even in the cases where users hurt the experience, we tend to blame the higher org for not resolving the conflict. "There are people bullying on the platform" -> "Why doesn't Google get rid of the bullying behaviors?!" instead of "Why don't people stop bullying?"
I think we also have a tendency to take it to the next level, which is often government. If people are scamming me through Gmail, we can tend to not think it's the fault of the people scamming or of Gmail but of the government for not forcing Gmail to stop the scamming or the person from doing scamming directly.
So I appreciate you bringing the attention back down to the ground level. While I disagree in that it would be only the users, I believe they (we) contribute to the problems as well as Google and the government and many other entities.
