That lateral load shown in the video is a test of nothing, really. That force vector isn't something that happens in riding.
However, some of this thread is talking past each other. Manufacturing in China is diverse now. You can get whatever level of QC you want, from the type that Spec and Cannondale want (just be wary of where your IP goes, that's a cultural difference) to knockoff stuff with no QC. And even with the knockoff stuff, some of it is perfectly usable. Even the knockoff watches are perfectly usable.
There is no pedigree with the knockoff frames. There are plenty of vids on youtube of what you get with replica Colnagos (no lugs) Venges (poorly finished interior layup) and Williers. However, none of those videos prove that the frames are dangerous, just that they are not made with the care and advanced layup of the better bikes.
I rode a generic bike (fm066) for 2 and a half years, went down a couple times on it, and it was fine. But the ride, although perfectly acceptable, wasn't as refined as other non-generic bikes that I've been on. Of course, it was 1/3 to 1/2 the price.

It is true that this is something that does not really happen when riding but this is definitely a way to 'test' a frame's flex. Certainly a stiff enough frame will not flex like that.

They do. It's normal. I have carbon, titanium, and aluminum road bikes that all do it, and a carbon TT bike that appears to be the worst.

Maybe I am lucky because mine do not.
Last I checked, Tarmac and Allez have a sticker "handmade in Taiwan". Historically, Chinese could care less about quality, whether it's a frame or grape juice. As a matter of fact they could care less about their own nation with such population. Last thing they are going to do is worry about quality control of the frames they slap together.
In contrast, Germans, French, Swiss and Italians take pride in anything they produce. They take their sweet time, that's how they were brought up from generation to generation.

Planet X don't sell chinese counterfeit R3/5s. They sell chinese open mold frames - there is a difference.

So why do German, French, Swiss and Italian companies outsource their frames to get made in China?

I illustrated a broad statement about culture differences. Production of carbon frames is the not the pivot here. Not 100% of frames are made in China, needless to say it's not about the origin but lack of quality control. When it comes to knockoffs and open mold, quality control must be non-existent because no one gives a shit.

Oh I agree that a lot of fakes have no quality control whatsoever (though I'm not so sure about open molds) but the issue is a lack of accountability, not simply the location of the factory.
That's why the europeans who you say take so much pride send frames out to get made by the Chinese - because they know they can do a good job.

The main reason they send frames out to get made by the Chinese just because that's cheaper.
