Plainly, you don't know what you're talking about.

There are standards to prevent such nonsense from happening. In order for an electronic device to be sold, it has to pass international standards to ensure it doesn't do exactly what you think could happen. In the US, that organization is called the Federal Commucations Commission (FCC) that ensures that products meet the standards set out by organizations like IEEE. You can't just make whatever product you like, claim it meets these standards, and release it into the world to fuck over whoever bought it. It doesn't work that way. For example here's an article on the Switch's pro controller passing certification. http://www.ubergizmo.com/2017/01/nintendo-switch-pro-controller-fcc/

Low quality video cables cannot mess up a display. That's impossible. All they do is carry a signal, and with HDMI, since it is a digital signal, you either get a perfect image or you don't get any image so long as the cable is within a certain length. That's why a  6' $5 HDMI cable is just as effective as a 6' $100 HDMI cable so long as they meet the same HDMI specification, and again, if the're FCC certified (and they are), they have to meet the spec specified on the cable.

This is anti-consumer nickel-and-diming horse shit. This would be the same as if Sony required all PS4 use special Sony-branded PS4 HDMI cables that inconveniently cost $100, and locked out all other HDMI cables. Even if it came with one in the box, people would be justifiably outraged and you know it.

If you think the FCC certifies every 99c Chinese cable that's resold on EBay and Amazon, it isn't me who doesn't know what they're talking about.

Care to tell me how Nintendo expects to prevent users from pluging in USB-C chargers bought on ebay? They've already announced such devices can be used to charge the system on the go. It charges with "any standard cable according to official statements". So please go ahead with a technical reason why they let you use just any standard cable to charge it, but not for video output?

If they wanted to prevent anyone from using just any old cable, they wouldn't have used a USB-C port. So again, you don't know what you're talking about.
