If PTP is ultimately going to happen, but is delayed for political (and not technical) reasons then we should think a bit deeper about whether that is the right thing to do or not.
If the delay is to give people the time to upload their content without it being included in PTP (which I think is an argument made by some) then we have to acknowledge the relatively very small amount of people who will have this choice (ie. people who already know about the project), and the even fewer who will actually want to exercise this right.
Arguably, the sooner PTP is implemented, the sooner we’ll know if it will work as intended or needs to be tweaked. It may be better to address any issues resulting from implementation sooner rather than later, and also perhaps better to reap the rewards of incentivising data (and ultimately bigger and more useful network) sooner too.
