Well seems they actually do if you read the whole thread. But it's not so obscene.
Honestly can't blame them too much.
Seems they offer superior quality at a not too high price for something made in EU which is, especially at this time, very relevant.
I'm glad if they capture those customers that would have fallen for perfectly normal cables sold at 20 times this price.
The "No nonsense" in their homepage seems to be a bit too much marketing but for sure better than the "Full nonsense" of other expensive audiophile stuff.
Their audio cables are probably going to be very interesting, will consider them in the future.
About the USB cables, this one specifically I probably wouldn't buy it.
You can find it for 59€ here in EU (that's the standard, non discounted price) and it's a bit too much for any 2mt USB cable in my opinion.
Even considering the high quality standards and lower risks.
The "secret sauce" of this cable it's in the datasheet
https://supracables.se/datasheets/en/USB-cables/usb-2_0-a-b-datasheet-en.pdf:
The trick is as always, the shielding, separate for each pair of leads, correctly twisted leads and the exact impedance alignment of 90ohm, which is absolutely vital for USB applications for jitter-free transmissions. Supra USB2.0 will reward you with a dynamic, rich and detailed music experience. Undoubtedly!
The big delta seems to be the additional shielding for each pair of leads; AFAIK in general the other USB cables doesn't have it.
But does it matter for a 2mt cable? I'm quite skeptical but for sure it doesn't hurt.
I guess it does for >5mt as 90% of USB cables over that length suffers signal degradation, often so severe that is causing signal loss.
I would definitely consider the Supra USB cables for 5-15mt lengths; at 15mt it's a miracle to find something that works, even USB2.0
Can't judge about the correctly twisted pairs and perfect 90ohm impedance; to be honest that's something I would expect from any correctly manufactured cable with proper materials.
But maybe I'm wrong and at least it shows a dedication to quality.
Let's not comment about the music experience, pure marketing sauce
There are a few things which I don't like about this cable, considering the price.
First the connector; it's bulky and die-cast.
At this price I would have preferred and expected a removable one like they use in their much more expensive Excalibur series.
In general it's much more practical and probably more durable the no casing solution used in the expensive (23,5€) Chinese Amazon cable I bought on Amazon, the magnificent (I'm joking) Tertullus:

It's a pure joy to plug it in the PC and the DAC.
Second, the beads.
Why there are no beads?
It's one of the few things that really makes a difference in filtering upstream noise form the source (if you have, like me).
My cheap/expensive Tertullus have them already.
Maybe the additional shielding makes them no/less relevant but I doubt it.
Third, the CE & ROHS declaration:
I understand that you can self-certify if you are very confident in your manufacturing process but at this price I would have expected 3rd party testing.
Plus I don't think this CE Declaration of Conformity is even proper; I'm pretty sure it's mandatory to declare the EU regulations which the product is subject to and the related standards.
Love the EIA-364 standard for the mechanical robustness of connectors but where is the EMC?
This makes me feel a little less confident on the quality side but at the end it's more likely just administrative paperwork than else.
Anyway that's what I was expecting to see, it comes from another USB cable EU DoC:

I recently had to buy a new USB-B cable here in Germany, when I added the HS02 filter.
Have a large stash in Italy due to the old printers, scanners, USB HDD enclosures but none here.
There are almost no physical shops left here, if you don't know exactly what to buy the only option is Amazon.
Since there's theoretically no reason to spend more than 5-10€ on a 2mt USB cable I bought, tested with MTA, sent back almost a dozen.
They are all incredible crap today, keep your old USB cables as they are valuable.
The new ones are from straight out faulty to poor filtering of the noise up to polluting the USB bus.
Only one decent, at the level of the DAC cable, was just like the others but costing a whooping 16€.
That's how I ended up buying the funny Tertullus which at least has the no-connector advantage, the beads, it's fancy (if that matters to you) and works a bit better than the DAC cable.
For just a few euros more it's a decent buy in my opinion and more than enough for anything which is not super hi-end.
The better quality is probably irrelevant with my Yamaha amp but I love that it measures better
Against the already excellent Fosi ZD-3 cable it has 1-2db less noise which brings the ENOB from 17.8-17.9 to 18.0-18.1.
