Major vendor cables, and the delamination was one connector's "finger" so not really cable-specific. The second connector looked fine at casual glance but there was something wrong with it as it wouldn't even hold connection with a USB2 device - too much slack.

I don't recall having this issue with any of the connectors it replaced. I have devices that are close to a decade old and all their USB/Ethernet/HDMI ports are still working just fine.

It's a terrible design that prioritizes form over function/reliability.
