The OP is talking about big orgs, so it's kind of a dick move to hijack the conversation and proclaim your agenda to be morally superior. You don't have to put other people down to make your point. It's childish, counter-productive, and you leave yourself open to criticism that your work is also The Wrong Thing because you're not volunteering for some greater cause like helping sick and dying people in developing nations. But I guess if a desire to be better than everyone else motivates you to do some good then I guess it's not a total loss?
