That is because "PCM" is an archaic name for "digital".
(PWM/PDM were similar archaic terms/schemes.)

Not so. They are all more specific descriptions of the digital coding used.
"Digital" is simply a more generic term.
It's the same as saying FM and AM are both analog "radio broadcast" methods.
Some people need to understand the difference, and some don't care.
