Morality and justice are a pretty important topic among geeks, and geeks were the best salesmen of Google at the begining.
We needed it. Internet was going to be this incredible place were we would all share and learn, create communities and make people closer to each others. Money people didn't understand it, technical person did, so we though we found a place were finally, we could create such a thing.
Of course, it was bs.
Worth pointing out rules are made, usually on two premises: should we and could we. Should we: is it morally sound? Could we: good intentions and morality notwithstanding, can it be enacted workably, to achieve intended effects and create little or no unintended effects?
