I'd certainly agree that open source offers the potential for independent verification of its nature, how many of these applications and libraries have been examined in detail by those who have the deep expertise to spot a subtle flaw and how many are just taken at face value?
The whole thing is frankly a cluster frak.
If I owned any server hardware, chances are it would be in a rack in a datacenter. What's to say somebody hasn't walked in, flipped a badge and taken my SSL private keys? In fact, that's quite probable.
Certificate Authorities are almost certainly compromised. Why bother with one at a time when you can just force the vendor to hand the keys to the castle over? Sign your own certs, MITM anyone you want.
For example, now I worry the security model of WebRTC has been compromised by NSA, because it has the potential to offer very secure P2P conversations to the masses (at least 1 billion users - and that's before IE even adopts it in IE12, hopefully).
Whatever channel you use might be compromised, if you cannot control both ends.
Phones don't record conversations in the pocket by default yet, but it's not inconceivable when computing efficiency improves that recording is always on, and keyword data is saved by default. Handy if it can creates calendar markings from verbal agreements...
And with Glass, video too.
So meeting in person is getting less secure as well.
Glass adds the perversion that you don't have your say regarding surveillance of society, anymore. Your "friends" will do it for you.
Only solution: Get vocal whenever you see somebody wearing Glass.
Even when they don't, it's probably easy enough to disconnect the battery on your own.
I'd say it's true for everything that's not open-source and doesn't allow for proper public key encryption. (Assuming that public key encryption is still holding up.)
