Interesting. I only stumbled upon one of his repair videos a few years back — was frankly blown away by his meticulous identification and cross referencing of specific chips, his ability to replace surface-mount components.
It left me with an appreciation for someone who can dedicate themselves to this depth of esoterica and make something I thought impossible look ... doable by an enthusiast?
But from your comment I wonder about that audience you mention: anti-Apple.
Because something that I also took away from his videos was this sense that technology, and I'm talking about the day to day things in our lives, has gone completely beyond any normal person's ability to repair, diagnose, or, really, understand at all.
I was careful not to say he made the repairs look easy — he made repair look doable but also underscored just what the layman is up against (SMDs, obscure codes on chips that are little bigger than fleas, specialized tools to open cases, paper-thin ribbon cables, etc.).
I think his audience is broader than just anti-Apple. Perhaps they're upset about all of the ways in which we have become enslaved to devices we can't understand.
