Yes, we are.  Space, not time, separates pixels, just as time, not space,
separates sounds in music.  In both cases, the signal is a variation in the
carrier; no variation (i.e., DC) means no signal.

No, they're talking about the properties of individual measurements of
individual pixels. The "signal" that you are concerned with is formed by the
aggregate of those measurements over space or time. But the noise that
they're squabbling over happens on an individual measurement.
