I once heard that root causes are almost never fixable, so pretty often the best that can be done is a few levels up. The root cause of anything is probably something like mortality, human frailty, the laws of physics. We are very far from fixing any of those. Twitter on the other hand can be changed, and probably some people on this very site work at Twitter and can (and should!) make socially responsible changes. It's not the root cause of anything but it has plenty of influence.
