Fair enough, I'm not arguing that they're obligated to or anything, I just think it would be nice. I do suspect that catalogue matters much more at this point than any tiny competitive advantage they get through better encoding. And they've certainly been willing to share advances (like VMAF) in the past - that's why this tech blog exists, after all!
