Second: This "will help startups compete against more established players." How so? Now start-ups are going to have to pay for preferential access to serve their content too. Big players will always be able to outspend these startups and in a way reduce the exposure of any new service. This is not so good for everyone (well except the titans).
Once AT&T can charge the remote origin for timely, reliable delivery of data to end users on their network, what makes you think they'll restrict it to just the handful of most popular services on the internet? Why not apply it to everyone sending data to users on their network from points off of it?

Well, as long as they are setting a popularity threshold before they start the "pay or be stalled" extortion, it'll make it easier for firms that haven't hit the threshold to grow against firms that have already hit the threshold.
(It'll also make it easier for AT&T's own content services -- at least when targeting users on AT&T's networks -- to compete against both established players and startups, because they'll never have to pay the extra toll, while established players will, and startups will know that it is coming when they get popular enough, and have to account for it in their model.)
Of course, they'll use the additional money to offer you similar services to the ones that they are charging other people to provide you, and they'll offer you a lower price than their competitors can in the face of AT&T tolls -- say $X+1.5N.
