I don't even dislike the pitch, tbh. Rarely do I view these posts as innocent / without-pitch. So seeing the pitch is almost appreciated by me, as at least he's trying not to hide it.
With that said, I wish he'd have gone into more of a pitch - specifically why Keybase might be unable to suffer from this specific problem. Or at least, why the attack surface area is smaller with Keybase, etc etc. He goes into a bit, but not a ton, I could have used more.
