The propaganda framed it like sites like Netflix would be really fast because they could afford to pay for it and startup competitors would be very slow, but economic incentives would have actually caused the exact opposite. A startup video hosting site is of relatively no burden to an ISP compared to a behemoth like Netflix so they would have no reason to slow down the startup speeds. If the startup succeeds because it has a competitive advantage to Netflix, then when they become big they get a new customer they can bully into keeping their speeds high.
Yes ISPs will take a cut of the fees they charge content providers, but they will also be able to pass those savings onto the average consumer because the Netflix customer, who is already using most of the internet bandwidth, is helping pay for the service connection. Market forces would force streaming services to go up in price and ISP costs to go down. It would be generally fairer.
