This line of argument is kinda weak. Personally I agree with the end goals, but the argument isn't compelling. Realistically these companies don't have much choice, and these businesses end users for the most part (the 99.99% that aren't technophiles) don't really care that the NSA is snooping.
I think we need to step back from hoping that business will protect the people. The people will protect the people, and if the people dont, a for profit entity wont (and shouldn't) step in as guardian.
"Realistically these companies don't have much choice"
Of course they do. They can comply or not. If they do not comply they may face court. Of course it is impossible to say how that court would go since none of them are making a choice to stop being co-conspirators.
