Quote from your pdf article page 2:
Since then (the Iraq war 2003), anti-Americanism in France has been steadily high ...
So it isn't significantly worse in France than in other parts of Europe yet in France it is "steadily high" ... hmm
As for why Apple sells well there, Apple sells well everywhere (great marketing and usability), even in Japan
.
Just because you don't see anti-Americanism/anti-MS in the UK, doesn't mean it doesn't exist.
As I said, I agree that those factors listed by "function" and "Arwin" are playing a role in marketshare, but I think the reason they may be advantages for Sony in the first place is that perhaps MS has done the market research and found that further investment behind the xbox brand above what they have currently done would produce diminishing returns due to anti-MS/US sentiment.
Maybe that will change in the future.
Maybe I'm off completely and MS just hasn't had support ($) from HQ to grow the brand properly in Europe and Japan.
Who knows.
One quick way to nullify any possibility of anti-MS/US sentiment though would be to enlist a respected hardware partner that doesn't have any stigma to overcome.
Samsung
Matsushita (Panasonic)
Sony
Toshiba
Labeling the xbox720 with any of these brands would elevate the image of the box in peoples eyes (even here in the "home-field advantage" US), produce a higher quality engineered product, reduce the likelihood of future RRoD, and nullify most/all of the anti-US/MS sentiment that may be holding back sales.
Now doing this one step doesn't erase all of MS' problems of competing with Sony in the region, but that would take 4 out of the 7 advantages immediately off the table (assuming BR player is included in xb720).
Then it's simply a matter of working out the localization issues across the globe, bringing live feature parity, and continuing to fund development of unique IP's and reaching out to more risky/artful/out-of-the-box IP's can also afford to be developed given the broad nature of the expected marketshare by following the steps above.
Path of least resistance would of course be to team up with Sony, let them design the hardware (not cpu/gpu), reap the rewards of their distribution channels, and localization teams and let the profits roll in for both companies...
Outside of this pipe dream, they can take advantage of Samsung or Panasonic's good name/brand have them design the hardware and utilize their distribution channels and marketing teams.
Either way I think it is safe to say that branding (MS/US) is playing a roll in sales for certain regions. To ignore this and pretend it doesn't exist is to be blind to the world we live in today.
