Just because it is used for other reasons doesn't mean it can't be used to fuck with repairers too. Apple has a long history of doing just that. I take it you are not a fan of Louis Rossmann?
Louis Rossman is a moderately competent microelectronics repairer who found his calling as a YouTube entertainer and low-grade anti-Apple meme celebrity. He produces entertainment content where Apple features as 'the bad guy' and many people find it utterly captivating. He is barely qualified to have an opinion about why complex electronics products are made the way they are.
