I would only sign such things to be a jerk. As some sort of long dragged out joke that probably only I would fine amusing, and everyone would think I was crazy because of my insane devotion to the project.
For example, the most hilarious situation I can think of, is one where you convince Microsloth to remove it, then later convince them to bring it back, then after all is said and done, make a new petition that states that we're all very sorry, but we've changed out minds and decided we're better off going with our initial feeling.
Then maybe just maybe, write them one more time saying,"No, you are right, we want to be monitored, we want to pay to play used games on our XBOX, we want large corporate entities watching over us, making choices for us, adverting to us, and collecting data on us. We want them to have cameras to scan our rooms and speakers to listen to us. Technology is only a good thing, it's paving the way towards a future unlike we have ever seen before, and we can trust in the powers up top, and the law that binds them, that none of this technology will every be used illegally against us, we can trust in our nations leaders to adhere and stick to their constitutions, something something something.
What was I talking about again? Oh yes! Pickles!
