It's a legitimate question, although maybe not worded perfectly. I care whether it's me or someone else who ranks for a keyword, maybe my site is better, and I (like anyone else rational) would prefer to make the revenue. I think understanding what ways you can gain links that is still acceptable under Google's guidelines is a very important thing to know, and truthfully pretty difficult to figure out. If you try to build a really great product and never tell anyone about it, I don't think you will last long enough for Google to give you the proper recognition.
