Major Chinese manufacturing companies like the ones for Apple are partially owned by the Chinese government so yes that would put China on the blame game.
I disagree, and I will tell you why.
Apple willfully chooses who to use to manufacturer their parts.
If they are using the same cheap Chinese crap as E-machines, then I think it is safe to opine that the myth of hardware superiority is exactly that.
A myth.
I recently replaced the memory in my iMac, only to discover that "Apple Memory" is in fact, cheap commodity Hynix memory.
Unlike others, I place any and all hardware faults squarely on Apple, because that is where the buck stops.
Apple abandoned U.S. manufacturing, assembly, and Q/A (my came directly from China).
Prices have not come down commensurately with the fact that they are using the same parts as $400 PC's and that is why the stock is a tiny bit more than $14/share now as it was in the early 2000's.
Apple is making the choice to use crap. It's not as though they are contracting with premium suppliers at premium prices. They are choosing to pad profit margins and give consumers cheap hardware, because they think they have a sufficiently religious user base that will justify their decisions no matter how absurd.
For the most part, they are right.
For the rest of us, though. Those who retain mental autonomy and who don't subscribe unrequited loyalty to large corporation while touting our superior intellect ... I think we see that all Apple hardware faults are the direct results of decisions made by ... Apple.
I do not believe that a gun is forced to their head to use cheap parts, and given the amount they charge for their hardware, they could certainly afford to use better parts with more stringent quality control.
They simply choose not to.
