Nothing to do with that. Authentication is an essential pillar of a security app, and the ability to effectively authenticate is an important component of opsec. If SMS is compromised (and it is not hard to imagine given how protective govt is about SMS exploits/sigint) then the authentication aspect of any app that relies on SMS is also potentially compromised. Weakest link and all that...
