Because you're clearly presenting it as a defense of PGP on a thread from a presentation clearly delineating breaks in it using exactly the kind of complexity that the article you're responding to predicts would cause it to break.
I think this supports my contention that we spend much too much time quibbling about cryptographic trivialities when it comes to end to end encrypted messaging. We should spend more time on the usability of such systems.
