Sorry to get off topic here. That I'd interesting. I figured wizards would have dumped that domain name. Why pay for something that isn't even your company (it was over a DECADE ago).
Less than $10 a year is trivial for a company compared to even the barest glimmer of future value from a once-famous name. If even one person a year hits TSR.com because they vaguely remember playing D&D when they were young and goes on to buy just a single book, they're already profiting off it short-term. Also, if they dropped it, it'd be snapped up by a squatter—or, even worse, Totally Slutty Rangers: The only site where half-elven hotties show off their enhancement bonuses! (Most of them are probably not using the inherent bonus rules.)
