I'm unclear on what stance I've supposedly retreated from. My position is that an opt-out is not necessary under current US law, but that it wouldn't be the worst-case outcome if new regulation were introduced to mandate it.

By "default" I refer not to the most common choice, but to the outcome that results from inaction. There's a bias towards this default even if the majority of rightsholders do opt to use Nightshade (which I think is unlikely).
