Security by obscurity isn't sufficient by a long shot -- and you can't rely on it -- but that doesn't mean it's without value.
Obscurity may only buy you time while you fix your security problems (before someone stumbles across the mistake you've made), but if you can manage to correct flaws before they are exploited, well, that's a good thing.
That said, Wire would do better to share enough details to show that they are putting real work into security and encryption. Compare Wire's security detail with something like Crypho's: http://www.crypho.com/features.html
They're still omitting plenty of details in their implementation, but it's obvious they have a strong focus on security. Wire doesn't really say anything (yet).
