This is another factor to consider when buying Apple products. Let's face it, Apple is a control freak. It mirrors Job's personality. When you buy into their ecosystem, you buy into this attitude. If you don't like it, don't buy Apple products. Period.
Sucks for the repair guys, but I'm sure they can run a successful repair shop for other electronics and non-Apple devices. Sure... Consumers lose when there is lack of competition, but Apple has a right to control everything they do, end to end. Consumers also have the choice to refuse to buy Apple products when they know they will not have as much choice in repair.
Instead, consumers flock to Apple suff even though there is a premium cost in all aspects of ownership, from initial purchase, to repair costs, to costs of accessories and cables, and everything else involved. Obviously, what Apple offers is still worth it to them, and they are willing to pay more for everything. But this is no secret... You know this going in. I'm sure repair shops know they walk a fine line as well especially if they are not "official" with Apple. Especially those that publicize to the public how to repair everything themselves.
If anything, hopefully the publicity from this will make more people aware of the way Apple works. It seems that nobody cares, alas, none of any of Apple's past behavior seems to make any difference. If anything, it has only served to embolden them.
