I opt into one and the other is done to me. These two things are not the same.
One is blatant merchandizing of social interchange (or whatever the fudge they call it) and the other involves secret courts and secret interpretations of previous legal decisions. Guess which one the fourth amendment was specifically put in place to prevent. Guess which one shreds the fourth amendment.
But it's all good: as long as hopey changy can keep the laws away from the supreme court, it's technically legal. And our government would NEVER lie to us. And if they did, it's for our own good.
But keep on supporting endemic surveillance; after all if you're not doing anything wrong you're absolutely safe, and that's the important thing, right?
