The panel had to rather stretch the concept of the UDRP to reach this decision... the policy was intended for dealing with cybersquatting on a trademark rather than this sort of hijacking, and it seems somewhat questionable whether the complainant had acquired any sort of enforceable trademark rights over the string "2E". Merely using something as an Internet address doesn't cause trademark rights to be acquired; it must actually be branded as a source of goods and services that is recognized by the public, something not really clearly demonstrated in this case.
At any rate, the Demys article ends by saying "Given the scope of potential attacks and damage, it is now imperative for businesses to consider the merits of outsourcing domain management so as to ensure continuity and minimise risk.", which seems a bit self-serving given that Demys is a consulting firm devoted to such management. Actually, all that's needed to prevent such hijackings is a bit of common sense and a minimal degree of attention; just make sure you keep your WHOIS contact info up to date, and that you keep track of the expiration dates of domain names to make sure you don't lose any you don't want to drop. And if you *do* decide to let one drop intentionally, check all your WHOIS records to make sure you don't use the dropped domain as an email address.
It also helps to avoid registering excessive numbers of domain names in the first place; if you use logical subdomains wherever they make sense instead of getting a separate domain for every silly gimmick and temporary event, you'll have a much smaller management problem keeping track of them.
