No, that was only half of the point of the video: legitimate cables have actual functionality to justify their cost
The other point is that there are differences in construction quality -- thickness of wires, cleanliness of solder, design of strain relief, etc -- that affect performance and longevity.
Everybody have enough junked cables that they can relate. (Yes, I realize the cheapo Apple Lightning cables fray too). I have piles of failed cables and accessories from "name brand 3rd party" like Anker, Monoprice, Aukey, etc, to not fall into that trap again. If im buying stuff with high functional requirements, no cheaping out.
