Yeah, right . . . Some DU lice condo probably thought it would actually hurt FR if we had to stop posting Onion articles and so complained to them. We can probably expect more of this, imo.
INAL, but it seems like a complainant who doesn't tell everybody else who's posting lots of his articles to the web/usenet/etc. to stop doing it, simply doesn't have much of a case -- particularly when he's been notified that it's going on (not that FR should go picking legal fights with everybody out there, either!).
Oh, well . . . Personally, I never cared all that much for the Onion anyway, the liberal POS!
