I'm sorry, sorry if I came across as bitter - I am not (over this? hah!).
Apple are not obliged to sell anything to anyone, period. People may LIKE them to, but they have NO obligation to; imagine the precedent it would set... the avalanche of requests for parts it would set off.
No. Forget it. They're NOT obliged, no matter what people daydream is fact, it ain't. Period.
I see your perspective, but Apple (or rather AASPs) used to sell parts to end users to fix their own machines. I quoted Anandtech, a famous tech website that is decades old now. They broke a Mac Pro during review and an AASP proactively reached out to provide them with a part, with a price of course. This leads me to believe that there is something fishy with the subjectivity of the AASPs Linus approached, or that the corporate headquarters changed stance on user repairs. I think it is the latter, which is what's upsetting for me. I fundamentally support people who make every attempt to empower themselves to learn, tinker and repair for the good of themselves and the society at large.
