A bit more objective than the other guy: their lab testing seems to be inaccurate at times and the way they correct mistakes they spot is questionable (for example just adding a comment and pinning it on the video). Also it seems they sold /auctioned something that was not supposed to be theirs to begin with. Some prototype waterblock. Also it seems there are two different stories about the issue and the compensation for the company who owned what was sold. And up until now, the story that LTT gave out seems to be the dishonest/questionable one.
I think the “problem” for those people is that the game broke out of its bubble. nintendo, from soft and also larion up until now all had their own bubble of fans. Larion broke that mold and even people who have nothing to do with the genre celebrate it.
