I forget what this is called, but basically you're saying "what you're doing is just a drop in the ocean, so why bother?" Or, worded differently, If you can't do everything, why do anything?
I said I was "too invested" in my gmail, but that's not the whole picture. I also, rightly or wrongly, have the opinion that my data inside my email is relatively safe without a warrant. That also being said, I'm not ashamed or concerned about any of my activity (though yesterday I was defending the rights of muslim women to wear a Niqab if they chose, so I'm probably on a list somewhere now).
My actions are less influenced by the concept of broad privacy and more the concept of encouraging what I perceive to be good business practices and discouraging what i perceive to be bad business practices, as much as one person can. I do my best to be a fickle online consumer.
