Maybe. But I believe the conversation at the time was about how FB tracks its users and what data it uses for advertising purposes, not about WhatsApp's encryption, or lack thereof. I meant deliberate in the sense that the question was worded in a way that made it easily dodge-able with a "no, we don't use your encrypted WhatsApp messages for advertising purposes", instead of "yes, we read the content of your FB messages for advertising purposes."

> Him admitting they serve ads based on Messenger content means nothing, we already know that they do.

I don't think that has been confirmed (source if so?), and I think that's what the question should have attempted to confirm.
