CNET does not find interesting programs and request permission to distribute the application through CNET Downloads. Rather, they leave it up to the developer(s) to decide to offer the program through CNET Downloads, a free process that involves creating a developer's account on upload.com. If you want to see WSUS Offline listed on CNET Downloads, you may want to make the suggestion to the program's developer(s) and see if he/she/they would like to do so.
