His video was a paid sponsored video. There is nothing else to elaborate. He got paid to push the QC ahead of the Kemper which was the competing product. It doesn't take a rocket scientist to figure this out. It's not complicated.
Fact is he disclosed that he is getting paid for promotional videos and imo he had no interest in showing a legit comparison. The first video where he forgot to refine is even more proof that this is the case. It doesn't take such a high iq to understand that someone who sold commercial profiles would not forget how to do it properly.
Some people prefer a sweet lie rather than accepting the hard truth especially if they are emotionally/financially involved.
