Personally, I agree and we will have to wait and see what happens ultimately.
Amazon tried this a few years ago, and I believe they stopped doing this but I'm not sure. But if I knew or suspected that Amazon was trying to squeeze a few percent from me, it would make me less inclined to use them. I can't see how this isn't the case with Uber as well, if customers suspect they are being gouged. It would then open the doors for vast accusations like the twitter post.
