I work on the assumption that everything I do on Facebook platforms including WhatsApp is secure from random hackers but not secure from the Five Eyes.

Years ago in the Snowden docs there was a diagram of a link into Google's infrastructure where they could take the SSL off and put it back on again, fooling people into thinking everything said about SSL and HTTPS implied actual privacy.

Since this is a taboo, 'not this again' type of question, can you think of ways to ask this in such a way they can only lie?

For instance, what guarantees can Facebook offer to their users that their messages are not being mass intercepted by Five Eyes?

I am fine with police with a job to do getting someone's texts, e.g. if someone is in a road traffic accident when they were texting on WhatsApp, I would gladly have the police get access to that person's data. However, the mass surveillance and the chilling effects that go with it are not good for society. It is a breach of privacy. If the government do such things it is still illegal. Even if they write laws that say it is okay, it is not. So rather than sweep this topic under the rug, I would like the answer from Facebook as to what they are doing and what they would do if their customers were subject to mass surveillance from Five Eyes.

I don't think it is unreasonable to ask this.
