Its all about full disclosure for ethical reasons. Can't say that about them white hats.

I don't know what this comment means. Could you, or someone else, explain it? Who are the "white hats"? Why do they have different perspectives on full disclosure than other people? Who are those other people?

I think hondje's comment was intended to be sarcastic, for the rest see

Maybe a riff on the burgeoning "green hat" practice of selling exploits instead of simply disclosing them, versus black hats releasing them publicly for free?
