It is a sad time. I can't remember who wrote it but they more or less said that Lavabit was a canary in the coalmine. I wonder if it will be "too late" or that we have lost the majority of our US based internet privacy when people finally wake up.
Maybe if the gov't started making pre-emptive arrests based on someones Facebook messages that the general populace will wake up and realize that they've traded a pound of freedom for a penny of security?
Do not rely on commercial services to protect your privacy from the government. The goal of any company is to make money, and since they have to operate within a legal framework, and they will either cooperate with the government or fold (usually the former).
The safest thing is to do encryption locally using open source tools (that can be checked for backdoors). It may be a pain in the ass to use, but it's more of a pain to decrypt, at least until the NSA gets a quantum computer.
However, the best place to fight invasive government surveillance is at the ballot box.
