Chris literally was saying it from the very beginning (you can watch early interviews, obviously he was being asked about it), everything that happens with progressive opening is what he said he'll do and he gave rationale for it which is summarized by what parent comment says.
That doesn't seem to address what the parent comment says; they're arguing that the rationale for the progressive opening doesn't make sense, not that it didn't or wouldn't happen. If I say "I'm going to work on feature XYZ at work today because the sky is yellow and grass is purple", it would not make sense to defend my claim tomorrow by pointing out that I did work on feature XYZ.
