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.
