iirc, it was in the back and forth from information from the DnDShorts channel, where he was talking about information from employee sources, because he had been reached out to by actual WotC employees, and there was a discussion about whether that information could be trusted or not because different employees were reporting different things (this would be WotC employees vs DnDBeyond employees, and the different teams within having different levels of influence and exposure to external products, which is normal). The raw numbers were condensed and passed along, that is not in dispute, but the comments and information that people wrote in the text boxes was not, and wasn't considered important information worth gathering or condensing. We know it was read by some people, but apparently when people on the design team asked for it specifically, they didn't have the comments.
So if you mildly disliked something, but not enough to make you actually click "dissatisfied", and then went to explain yourself in the comments, your "satisfied" was recorded, but your comments were not.
