Why is Louis Rossman put on a pedestal and seen as THE authority on all things Apple repair? Because he's high profile (in a YouTube context) and makes a lot of noise. So what? He's not KING of Apple repairs, as competent as he may be. He's highly opinionated, very negative and passive aggressive, and that kind of personality is repellant. A high view count and him knowing how much people refer to him, can only expand his ego, not that I know he's particularly egotistical, but this is a known pattern with high profile YouTubers.
Why can't people use critical thinking, instead if flying towards their "go-to guy" as a piece of steel does to a magnet, quoting their every word as some form of holy scripture? He's a bloke in a shop and he repairs things. Fab. Lots of people do that.
The internet. Ugh.
