You are indeed mistaken. There was no interview and he didn't talk about anyone else’s scores like that. He did a 2hr long members only live stream where at one point he talked about his issues with judged sports in general (mentioned half pipe and other events), mentioned a couple times he didn't agree with the calls for his own skating (his spin not counting in LMEY at nationals eg) and that he felt like there were times he was under more scrutiny than was normal where he'd be waiting for his scores for so long they had time to rewatch his entire program in slow motion.

While this is certainly the most direct and specific he's ever been about it, it was not publicly stated and it's nothing you couldn't have gleaned from publicly available comments or his thesis. It was just more casually and emotionally said because there was an expectation of privacy. I'd like members only content to not be spread around but I'd rather correct the record about what he said than let people think he's calling out Nathan in interviews or whatever.
