You do have a point, specially after the ELO Hell stream. However, what would your opinion be if he is just influenced by his unconscious bias?
In the case of ELO Hell, for example, because he finally got a sponsored stream, he would be more prone to accept the game, (on that particular day), and praise it, just because his overall emotions/state of mind was 'better' than other days, (dictated by an external factor), and he wouldn't know why this is.
Do you think that he's consciously lying, or maybe that he's such an incompetent at discerning why his brain is telling him what's good or bad, that would appear to everyone else that he's lying?
(I'm posting this as a hypothetical, I'm in no way defending his very suspicious actions.)
