That's rather hypocritical, why are you talking about Maniac Mode then, since that was literally a mode removed in the final version of the product and thus was clearly not intended to be played.
As has been said above, those playthroughs, even if they don't allign with your moral code, can still prove valuable insights and can still be learned from to apply to other playthroughs. The Typhoon Carter playthrough plays with 100% growths, which is just the same as rigging without all the resets. The chili one is 0% growths with critforges, because it uses existing game mechanics -intended or not- to play around the loss of stats.
Playing 0% with critforges is still a lower power level than with growths but without critforges. And they completed the game in 149 turns. There is a lot to be learned from that. If you cannot acknowledge that you can still enjoy playing the game your way, but you can't expect people to take your advice and tiering seriously, as it is incredibly linear and close minded.
