The NSA is keeping a record of everything sent over ISP channels. Someone at least potentially has these messages anyway. Anything sent over the internet has this problem.
That's a really good point, I hadn't thought of that. While likelihood of storage is much lower with internet traffic, it's still possible.
What is more important, that their is a model for storing data, that is _not_ advertisement driven and that does not vanish as long as you pay for it.
