Because it is "honest", and supporting the hard working people who make the softwear, who have bills to pay and children to feed.
This issue has been beaten to death in the past and the general concencious is that it's wrong, but if your gonna do it keep it quiet because you will soon loose all respect from a lot of people on this board if you admit to pirating the softwear.
So i'd change that statement to a theoretical one if i were you, otherwise you'll find less and less people helping you in your posts when you ask legitimate questions. There are people on this board who actually make softwear for a living (maybe not audio softwear), and they take these issues very personally (obviously).
I think people would view it in the same vein as if you went to circut city or whatever, guitar center, and shoved
neuman tlm103 (or whatever the model is) down your pants, and came home and laughed at all of the other "suckers" who actually paid for their products. "It's so easy to steal why pay for it?". I'm not preaching i really don't give a fuck myself, but i'm just saying don't go around sayin that sort of thing, here people don't like it.
It's taboo man, Sshhhhh.
