I've been reading your posts on Microsoft's monetization of error searches so I thought you may also find the attached screenshot interesting. You'll notice the URL was spelt correctly so I personally don't see a reason for the redirect.
Being third in the search race combined with control over the majority of browsers could offer some pretty tempting possibilities if ethics didn't hold you back ;)
Thanks for the note Peter.. many folks are beginning to discover the double-standard that you just did. Cybersquatting in the browser is apparently okay.. its just when you own the name that you're in trouble :)
You could argue that Google does the same thing when you type a Domain-Name into their search box and they don't always turn back that URL in their list of results. "The Line" is in this post somewhere.. it just hasn't been defined yet. MSFT and GOOG have probably crossed it in certain circumstances.. it's just that nobody has sued them for it yet so they take what they can get away with.
