The main reason WGA "works" (ahem) is because users needed to use Windows update to patch bugs/security fixes/getting the new Service Packs. Problem with OGA is...does anyone bother to update their version of Office? All that has to be done is download a copy of Office, crack it with the included crack, use it, and don't upgrade (there's probably a few hidden steps in there like block Office traffic with firewall and don't use Outlook).
