Why old folder icon for Mac?

I just downloaded the Endnote X5 trial for Mac. I’ve always been under-impressed with the Endnote website to begin with - not good for a software company to have an ugly website. But then the very first thing I noticed during the install was the old Mac OS 10.2 or 10.3 folder icon that accompanies the program. Why are you still using that icon? It’s a detail, sure, but it’s this kind of attention to detail that makes a poor impression.
