No, the problem really is a legal one.

But they can't, because of the legal implications of enabling the sharing of copyrighted material on their system.
"NVidia immidiately put out a rebuttal to these claims, and I'm not sure why they weren't reported along with this article."

"Films go at 24 FPS, but film also has perfect motion blur and the eye can harldy tell."
What's "perfect" motion blur?
The reality is that you _can_ see stuttering in movies if you look for it and the director doesn't know how to avoid it (which is, for example, one reason why you rarely see a fast pan in IMAX movies). I remember some of the pans in 'Sixth Sense' being particularly bad.
"This doesn't prove that they don't tune for 3DMark2003, though. Reading the report, it does seem suspicious, but I believe the tune would have to be specific to that particular benchmark."
In the past, to tune for a specific benchmark you generally had to detect the benchmark application running and hence your strings check might work (though any competent programmer can think of an infinite number of ways to defeat it).
3DMark03 used a timed demo playback so depending on your frame rate your driver could get different calls every time the benchmark ran. However, 3DMark03 uses frame-based playback and makes _exactly_ the same calls to the driver, down to the very last bit, every single time it runs: it is, therefore, trivial for someone to add code to say 'are we being asked to render with pixel shader xyz at camera position (0.512, 23.76542, -89.67325)? If so, we're running 3DMark03. For frame 1, we can ignore the first twelve rendering calls as they're offscreen. For frame 2 we can ignore the last eight rendering calls as they're offscreen. For frame 3 we can artifically clip anything outside this area as they're offscreen, etc, etc' That would give you a big, big boost in the benchmark, but the rendering would go wrong the instant the camera was turned away from the default position for that frame, and would give you a high value that bore no relation whatsoever to the performance that card would give in a real game.
And this is why frame-playback benchmarks are a bad idea: they're trivial for programmers to develop hacky optimizations for that artificially inflate their numbers. There's no definite proof that nvidia have deliberately done this, but the pictures in the web articles look very suspicious.
"This is just a semantics game. I guess there's no such thing as "identity theft" either?"
Uh, an identity is a unique item tied to a particular person: if you can "steal" that identity, then the original owner no longer has it nor has the ability to control what you do with it, yet faces the fallout from your actions.
Trying to compare dowloading an.mp3 of a song to identity theft or other real forms of theft does not make people take downloading "theft" more seriously, but instead trivialises real theft. Odds are before long you'll be more likely to go to jail for downloading a song than for committing a burglary.

Wow, we'd better all be fitted with wireless cameras so the copyright police can ensure we don't deprive the authors of their money!

If the management had considered the O-ring problem as serious as they considered the foam loss problem, the Challenger explosion would never have happened, as the engineers would have imposed the launch temperature limitation as a short term solution as soon as they were asked for a fix.

Every pound that weighs will be something like 0.8 pounds less payload, since the shell will have to be carried most of the way to orbit. Given that the shuttle payload to the ISS orbit is small as it is, reducing it further is really not an option: for heavy missions NASA would probably have to compensate by running the engines at an even higher multiple of their design thrust, which is likely to be far more dangerous than flying the current shuttle design.
Now do you start to see why these easy and obvious fixes _haven't_ been made? It is Rocket Science, after all...

Nope. There was already an active program underway to resolve the foam-loss problems... but any change to such an important system requires a lot of testing before it can be implemented. Just imagine if they'd changed the formulation of the foam and _caused_ a shuttle loss as a result.
NASA is a typical government bureaucracy and should be closed down, but comparing Columbia's bad luck (it appears that the foam must have hit in just the wrong place to cause the damage it did, and a few feet in any direction would probably have been survivable) to the Challenger management ignoring the engineers who were telling them that launching in that temperature was dangerous is wrong.

But on a number of occasions in the past I've avoided doing so by running an old a.out binary on Linux while migrating to new software which did the same job and was still supported. There are very good reasons for wanting to be able to run older code without recompilation.
Years back I tried an x86 Sinclair Spectrum emulator on SoftPC on a Tadpole Sparcbook: it was only running something like a 40-50MHz Sparc chip from what I remember, but the Spectrum games still managed to run pretty much at full speed. The main benefit of the Sparcbook for emulation, AFAIR, was that it had a real VGA chip so SoftPC didn't have to emulate that as well as the CPU and other components.

Mmm, yummy, only a "slight" increase in the evil carcinogenic particulates that the British government claim kill 10,000 people a year in this country.
The problem with that argument is there's still no clear way that the impact could have done enough damage for the shuttle to burn up. Either it was a very, very unlucky hit in just the wrong place, or there's some other problem which, in combination with the impact, lead to plasma coming in through the wing. For all we know, the wing could have been damaged prior to launch (either due to errors in handling on the ground or pure old age) and the normal stresses of orbital maneuvering could have led to the same damage on this or a later flight.

Not true. Almost every landing has been flown manually in the last stages when the shuttle reaches the landing site and slows to subsonic speeds. Every shuttle pilot flies hundreds of landings in an executive jet fitted with shuttle controls and HUD and modified to fly like a shuttle (aka like a brick) before they fly a shuttle for real. I can't find an official page, but here's one person's writeup of a flight in the STA: http://quest.arc.nasa.gov/people/journals/aero/rin go/shuttle.html
AFAIR there has been one flight where the crew flew manually all the way down from orbit (one of the first half-dozen or so, I think Crippen was flying), and one flight which did a 'hands-off' landing. Otherwise every other flight has been flown by computer until it went subsonic, then taken over by the crew.

"If we consider a country that has no copyright or patent system, then there is less incentive to innovate."
Yeah, if there were no patents and copyright we'd still be running our software on 8008 chips, since Intel would have no incentive to produce better ones.

Seriously, the idea that without copyright and patents there'd be no innovation is just silly; there are many, many reasons why companies produce new products, and copyrights and patents are way down on the list. Indeed, if there are half a dozen companies in an industry it's almost certain that they'll all be using so many patented processes that they'll have to cross-license their patents to everyone else anyway in order to get access to the other patents that they need; like other forms of regulation, patents then become just a government-sponsored means of keeping new competition out of the industry at the consumer's expense.
