I don't think anything has been skewed intentionally. When I do a build of the Camaro using Chevy's employee pricing (what I would pay) I come out to just under $43,000. If I build a Mustang using invoice pricing (the maximum I would pay) I come out to $39,000. That's a $4,000 difference right there.
No matter what, if I configure the SS/GT in the way I would order them, the Camaro is always more expensive. I agree that you do get more options in the Camaro which adds to the price, but still, that's real money.
I don't see any attempt to appeal to any fanboys. I think you're just splitting hairs, to be honest.
You have to understand that this is just a kid on Youtube who reviews cars. I don't think he has a fact checking team to make sure every number he keeps in his head is spot on.
