Louis Rossmann made a video highlighting a lot of the engineering problems with Apple laptops. His whole business is about repairing Apple laptops so he has all the reasons and incentives to defend Apple and downplay their issues.
How does this follow? He has developed a following around posting these types of videos which seems like a pretty sweet incentive for making them.
Not to say he's being dishonest or something, it just seems like a stretch to say that some random repair guy somehow has more to gain by (A) hoping 0.000001% more people buy Apple products by forgoing these videos so that he can repair a few more Macbooks than by (B) making these popular videos that net him subscribers and attention.
And he is internationally renowned for Macbook board repair and literally receives and fixes laptops from all over the world. He actively tells people to not watch his videos on YouTube and prefers Vimeo. I have no proof but I'd bet that his revenue from his YT channel is a small fraction of his overall income from his repair business and online e-store.
Ok sure, and the Earth is flat, Donuts are a health food, and lizard people are real.
