I see lots of problems in that blog post, mostly about how profitable netbooks can ever really be to a company that has made an handsome profit margin selling HW that is thisclose to HW that is much less costly -- yes I know that pretty much OSx86 hackintosh builder / advocate says they are NOT doing it to save money, but to "get a machine that Apple does not make" but the fact is that Apple gets a healthy upcharge for the machines it chooses to make. If it was just about some mythical "cut out the big profits of Intel" angle I would still say "baloney".
What does make sense though is to have IN HOUSE a team that is CAPABLE of out lining an alternate strategy. The kind of "hey, sit down with our guys, listen to their presentation, see if this is something you can do, if you can't (for your own internal strategic reasons...) then realize that we will be giving the same presentation to TI, or Samsung or whoever else has no qualms about fabricating some silicon for us that will end up seeing them 'advance' with us while you stay back to fight your 'battle' with AMD/Nvidia..." talk has PROBABLY ALREADY HAPPENED. Intel almost certainly has designed they'll either get on that bandwagon OR keep quiet about not doing so as they make some nice coin from Apple's other business.
And finally, I can't tell if I made my arguement clear in the above posts, but the fact is that right now CONTRACT fabricators are still not capable of reproducing the same level of technology that Intel is capable of -- their techniques are just too expensive (1) and even should some one like the Chinese pseudo venture capitalists be ready to pour the kind of dough needed to scale up fabs the result would be at best still a half generation behind the whole package of lithography / dieletrics / yield that Intel is producing right now becuase the rest of the world knows that basically everybody else is an "also ran" in that race:

1 -- the reason that Intel can support their "too expensive" techniques is becuase of the succes of their marketing campaigns on both the direct consumer level and also the technical marketing techniques. Buyers of laptops and desktops pay a premium for "Intel Inside" and that premium is funneled back to keep the Intel ecosystem healthy. Intel does spend more on R&D in all areas than any competitor, and that results in higher performance compliers, more flexible / energy saving peripheral chips, and basically a juggernaut that cannot be outflanked.
