Great. You're probably going to be Ground Zero for next week's version of the "run this program to see who looks at your profile" rumor, and the week-after-next's bogus virus warning about running the script.
I don't think they're censoring it -- The HTML on this page makes heavy use of the TABLE and SPAN elements for formatting. That seems to be something that makes it difficult for Facebook's link-grabber to read pages. I've encountered the same problem posting links to other sites with idiosyncratic HTML.
Facebook's reps haven't said the list is based on just on profiles you view, they said it's based on "people you interact with" -- there may be other stuff in there, like messaging activity, or commenting, or liking. Even if you don't go directly to Arrington's profile, you can be interacting with him in the newsfeed.
I think you're leaping to a bad conclusion. Keith's post mentions "computer-generated guesses" to fill in the list. Looking at the guesses in my list, they appear to be friends of friends. (The prefill list is probably using logic similar or identical to the logic that presents "people you may know.")
Find somebody on your mystery list who isn't a friend of your friends, and then you can get paranoid.
