The claim that "all bits are the same" is absolutely insane.
I do not want to pay the same rate when I'm downloading system updates or uploading a backup vs when I stream real-time video chat or work via remote desktop. In one case latency is irrelevant while in the other it's everything. It's important for ISPs to differentiate these bits and prioritize them accordingly.
Net Neutrality also raises the barrier to entry for new ISPs, which solidifies existing monopolies. A new mobile ISP that lacks the infrastructure to support video streaming won't be allowed to enter the market as they're obligated to serve the entire internet.
Cable providers won't have any incentive to offer channels over the internet as their users will have to pay extra (for the internet bandwidth it uses) when there used to be no limit (on cable). ISPs will likely have to invest in unregulated side-channels for distributing their content, increasing technology fragmentation.
