I’ve had this failure on soft-touch usb cables from the 2000’s, not related to movement, just in a box in room temperature storage they disintegrate like this. It was described to me as thermoplastic elastometer degradation but I’m not really satisfied with that vague of an answer. Main comment thread when I first jumped in to discuss it: https://news.ycombinator.com/item?id=28054090

I have a couple of USB cables from the 2000's like this, some of them original apple cables. But most are fine.

While some show brittleless, more plstics goes gooey and tarry - especially some ABS coating that makes the material more grippable,like computer mice or binoculars.

The link to the product says "TPU outer jacket". That's thermoplastic polyurethane, which is well known for degrading via hydrolysis: https://en.wikipedia.org/wiki/Polyurethane#Hydrolysis_and_bi... ...so it is a bit amusing to see "TPU Jacket Features Water, Abrasion Resistance" in the product description. PVC or PE would be far better and more common.

... Shucks. I should really have scrutinised the materials.

If you buy a consumer product labeled "military grade" you are buying snake oil. And not just snake oil, incredibly over priced snake oil.

"Military-grade" has a very specific meaning: it's at least 10x overpriced and painted black.

Why black? Shouldn’t it be camouflage?

What’s the advantage of using fiber optics for home networking over 10Gbe Ethernet?

They get less hot (especially the network adapters on the ends of them), can go a lot further, can be a lot denser (including being able to carry things other than Ethernet in the same bundle), and are a lot more future-proof (unless the cable jacket literally crumbles at the slightest movement in a few years).
