Preliminary calculations show that it would take decades to break this cryptographic separation [between a subscriber account and its associated network traffic]

The unnecessary rubbishing of Android VPNs seemed like one red flag in there. Is that another one? It seems both unlikely given the kind of traffic analysis that could be brought to bear, and very unimpressive that the hypothetical time to break it is measured only in decades rather than the multiples of the age of the universe that seem more normal when discussing things that are meant to be cryptographically secure.

But it would nonetheless be interesting, if Google hadn't shut it down last year as seems to be the case far as I can tell.
