I'd be fairly certain they have hardware backdoors into most things... My guess would be that there are multiple segments to the NSA, some of whom have access to the hardware level backdoors and others that want the software to be easier to compromise. I would suggest that if you are a target of the NSA the encryption you are using does not matter one bit, they will find a way to hack you and steal any keys to systems they need and you probably won't even know about it. I'm not so convinced about the mass surveillance actually being that useful to be honest, even with current tech there is just too much of it to help.
