Could this really be about the secure phone networks being hacked, spoofed and taken down by the FBI?

MI5 wouldn't get involved if this wasn't very serious already.

Has Johnston been caught playing treasonous games with the globalists?

I don't believe this is anything to do with whatsap.

WhatsApp is Israeli. They database everything in your phone and record all your conversations. It is a surveillance app disguised as communications.

there is no risk of sharing informations with zuck when you use whatsapp

it is a guarantee

so, as my friend libtard would say: fake news :)
