You got a copy without buying it. Sale was lost. Doesn't matter how craptastic it was. Developer is out money they would have gotten if you decided to buy that crappy shovelware. You didn't pay, you aren't entitled for that copy. All in my above post.
Nah, not really. It can't be a lost sale, since I would never buy it. Sure, I have a copy of it which I'm not entitled for, but still they didn't lose a sale because I downloaded it.
I did not download it INSTEAD of buying it. I downloaded it to prove that I can download something which I would never think of buying. But I see your point.
Another perspective: Say I make 5 copies of a game total. (Talk about limited edition!) Then I sell them all! Whoop! But one of the guys puts it online, and get's 5000 downloads. This can't possibly be 5000 lost sales, out of 5 possible. You see what I'm getting at?
