This is such a weird advice and it seems to come from a particular experience of software development.
How about using Booleans for binary things? Is the LED on or off, is the button pressed or not, is the microcontroller pin low or high? Using Enums, etc. to represent those values in the embedded world would be a monumental waste of memory, where a single bit would normally suffice.
