Well, I'm probably going to use the video conferencing company that offers the best connections at the best rates. If they have to pay more for more bandwidth then that's on them, not me (other than their fee). Their business model requires lots and lots of bandwidth. Mine doesn't.
But it's not about paying for bandwidth. Lets take his example.
Company X and Company Y are consulting companies. They both have a plan purchased through the cable company that provides them with a 30 Mbps download speed, with a clear caveat in the fine print that the speed could be lower due to network congestion.
Company X uses Adobe Connect as their means of teleconferencing. Adobe has an agreement in place with the cable company where they pay the cable company $X amount of money in order for their service to be on a "fast lane". Company X thus is able to do their teleconference at their full 30 Mbps speed they're paying for
Company Y uses Webex as their means of teleconferencing. WebEx has no such agreement with the cable company. As such, the ISP throttles WebEx's services over their network, causing Company Y to only be able to do their video conference at 10 Mpbs.
Company X and Y are paying for the same amount of bandwidth. However, because the service Company X is using pays the ISP money they actually get to use all that speed they're paying for. Meanwhlie, because the service Company Y uses doesn't pay, Company Y is hit with a reduction in speeds that is not network congestion related, therefore not geting their moneys worth.
This isn't a case of Company X paying for more bandwidth then Company Y....they're paying the same money for the same bandwidth. But because a company on the other end didn't give the ISP money, their data is slowed down, and Company Y is screwed out of what it's paying for unless it changes its teleconferencing service.
That arguably could screw up competition, but it becomes even worse if you imagine a scenario where Adobe doesn't just pay to keep its data in the "fast lane" (which is really just the normal lane), but rather pays an extra amount on top of that to be the exclusive teleconference service for that ISP...meaning if you use that ISP, it's either Adobe OR a slowed down teleconference service.
A scenario like that is not allowable under net neutrality ideals and principles. It's ENTIRELY possible with what Verizon and other ISPs have been arguing for in front of courts that allows them to discriminate against data for any reason they want and allows for them to demand payment from content providers or else have their data throttled.
