Everyone in this discussion has been led, most likely by talking-points marketing by the FCC and ISPs, to describe the destruction of net neutrality as allowing ISPs to “create fast lanes”.
This language was carefully constructed to sound like a positive, additive move: It’s building, not destroying or restricting. They want to offer faster service, not reduce the speed or priority of all existing traffic. Who could possibly be against that? They’re building fast lanes, like a highway! Everyone loves fast lanes! U-S-A! U-S-A!
