So Facebook are suing NSO for having hacked Apples or Googles software? My point is once end to end encryption is enabled -- no MITM vulnearabilities should exist. Kind of like how password managers protect your password -- not even they can see it. I think this is indicative that Facebook doesn't enable true end to end encryption so they can read messages themselves but advertise that they don't to attract the privacy dollar.
