Blizzard passed down the law that authors cannot charge for addons (yes,this created an uproar). Carbonite became free, but support has dwindled to the point we'll be lucky if it's updated for Cata. The team turned focus to more profitable projects (which is their right).
For the time being, the current live version has made it's home here at WoWI. I'd provide a link, but I'm posting from my phone on break. Just do a search for it.
