The more light on the sensor, the less noise but more possibility of blown highlights. Aperture and shutter speed (and available light) control how much light falls on the sensor.

I don't think I'd talk about it in terms of possibility; that suggests a randomness to something that you should strive to control. More light on sensor means less noise; too much light on sensor means blown highlights.

Of course, but I was pointing out the main problem with the wired.com triangle, which didn't even mention blown highlights.  It also doesn't mention diffraction as aperture decreases. It both ignores some trade-offs and gets the noise / light trade-off wrong.
