As far as slowing down progress, there is a danger of this happening without net neutrality as well. Consider the current state in Australia: you have ISPs that charge you based on GB of bandwidth used per month. For example, lets say your ISP signs a deal with Hulu so that traffic from them is free for you. Most people would probably not give any consideration to competing services because they will have to pay for bandwidth while using them. This is a huge advantage to already established online tv services that have resources to make these kinds of offers with ISPs. Meanwhile, new services that can't afford them get ignored by users despite perhaps having better feature sets.
