Thats a easy one I can answer in two parts:
Its free! Lots of folks have heard of it and use it, and its opensource.
We dont soley support it any more then we only support Ouka or FX Server.. CDex is just the only one we have a tutorial on.
If you like Easy Audio Copy and are familiar with it, then maybe you would consider making a tutorial for the site? We like to support free ware with no added extras in it, and like to offer folks instructions when we can..
PM me if your interested..
