That's not the greatest advice. I saw my mom charging her phone with a fat, meter long, USB-C cable. I asked her why she was using such a short cable. She admitted it was annoying to use. She said it was $35, but it was fast charging! It was a 100W 10Gbps cable.

I'd be willing to bet the vast majority of consumers do not buy name brand cables.

The majority of consumers don't do anything that needs more than 2.0 speeds and 30Wish charging. If they do, they can probably afford name brand cables.

In the next few years consumers will start getting laptops that need 60W, but most cables can do that now, and it won't be common for a few years now(Phones still had microUSB when I bought my laptop, many people have even older ones).
