I don't know if I would necessarily call that debunked. It only means the previously debunked introduced revisions to amplify their original points and the debunkers disclaimed that their debunk may be outdated in part or in full. Or not at all. I wouldn't necessarily assume that it's a forfeit. It could just mean the debunkers didn't want to invest more time into it. It's weird that they didn't link to the revisions though.
