The writing style in this letter is completely different from that on the TrueCrypt page. If this letter had been posted originally, the whole episode would have been viewed much differently. And why does the author of this letter assure readers that "As far as we know, TrueCrypt is utterly uncrackable", while the TrueCrypt.org page (or rather, the truecrypt.sourceforge.net page to which it redirects) screams (in red at the very top), "WARNING: Using TrueCrypt is not secure as it may contain unfixed security issues"?

EDIT: Sorry - as brazzy and NickSharp kindly point out below, the letter was imagined and written by Steve Gibson. As the HN title at the moment is "One of the TrueCrypt Devs Responded", I missed that.
