Questions like these always make me think of Dwight Schrute speeding towards a sales call that Andy Bernard is closing out from under him, screaming into his phone "are you saying you INVENTED PAPER?". I'm not saying I invented paper. You can be upset with anything you like. I'm not the upset police. But if the thing you're upset about (20 years later!) is the premise of the what is probably the single most successful project on the Internet, it's going to be hard to take the concern too seriously.
