> if they offer a "fast lane" at a higher price to everyone it isn't an "exclusive" offer and therefore would be allowed?
No, if it isn't an exclusive offer, then it would be tested under the test for which they seek input from the public under the next bullet point (which directly addresses the limits on the FCC's authority established in the D.C. Circuit opinion striking down the last Open Internet order.) The clear intent is to find a way to limit paid prioritization to the extent that is consistent with the limits on the FCC's authority established by the courts (because, if they exceed that authority, then the whole thing gets thrown out, which is why we are back at rulemaking on this issue again right now.)
