This really doesn't make any sense.
If the connection is really properly end-to-end encrypted, the wifi network security doesn't really matter. It could be an open network and still be okay. That's the point of encryption, after all.
On the other hand, if network-level encryption is important, no amount of encrypting one endpoint network is going to help at all if the connection then goes across the Internet through who-knows-what backbone providers and whatever Internet provider the end user has.
Or if they're saying that the connection is secure as long as it stays on a single secure network, that's barely interesting.
