So... it doesn’t change the actual argument.
It kind of does. I mean,it's not like they are practicing what they are preaching. If they really believe that sharing the wealth is the right thing to do then why are they reserving their argument exclusively to other companies and organizations?
None of these are arguments but one could imagine that the last one stems from "because we all think it's bad". Of course, absent justification one could just dismiss that last one out of hand instead.
