> yet they do more good than the moral critics do

Going to need a good source for that crowd having done more good than the frauds of even just their most-notorious members.

Masquerading as an altruist to justify massive management fees for running a fund of concentrated, leveraged positions is one of the oldest lipsticks on financial pigs.

Moral critics save a lot of lives by not doing. Sometimes not doing is the best moral option ex. I will not kill or I will not exploit.

And it does not come cheap. Someone who says "I will not work for Facebook" is taking a stand at the expense of significant personal gain.
