That's because every resolver operator would have been affected, not just Comcast, so the screams that Comcast (alone) was censoring NASA for <conspiracy theory du jour) would have been trivially dismissed.

Of course. NTA is a mechanism that allows folks who want to do the right thing to do so without incurring costs that folks who aren't interested in doing the right thing won't incur.  As more folks start validating, the playing field levels out and the need for NTA decreases.
