Not sure what your point is, here. I listened to it, and it was very interesting, but the speaker has actually implemented encrypted communications on Android, so he clearly isn't too worried about it being poisoned.

I'm not sure there is one perfect 100% answer for that question, but I might suggest "that was then, this is now?"

It is probably worth noting that the speaker (and tweeter) has had some significant delays in the last year while clearing customs.

Oh, I've no doubt that the authorities dislike him. The SSL certificate story made that clear. :-)
