I agree, that statement is pretty demonstrably false. Even Tor hidden services have weaknesses as we've seen recently. At least with anything concerning privacy and security, radical honesty is the best approach.

Lots of companies (particularly SaaS providers) make grand claims about their impenetrable security, but only foolish people believe that nonsense.
