I'd wager far fewer people will subject this to "constant rotation" than simply swiveling left to better interact with the screen, and keep it there. Given the geometry, which is rotating left / right off a fixed axis, and the long, wrapped, plastic armored harness, would take your bet that thoughtfully installed, this should not pose a problem under normal usage for the warranty span of the vehicle. The harness is quite long, and there should be very little rub. Even still, now that you've pointed it out, I'll be adding another layer of spiral plastic cable armor around that pass-through from the dash interior to the swivel area.
Also you're projecting quite a bit with that last statement - go watch and hear what John said again and explain where you heard "scam the SC like OP suggested" anywhere in why he stated you should keep the parts. It's one of those "DUH" observations anyhow IMO, you should always keep the OEM parts. You may love your mods, but a lot of buyers are wary of someone that does anything to bring a car out of factory spec, and you'll generally have an easier time selling without them and can capture some of that money back, if you're so inclined.
