I really didn't mean to encourage emotional manipulation, soulless optimization, listicles, etc., although I agree that a lot of writing online falls in that bucket, and it's even likely that the advice I uncritically quoted was aimed at that bucket.
I obviously should have thought more carefully and written more clearly.
But I don't think that "Write each sentence to give the reader a reason to keep reading" and "Actually provide value to the reader" have to be mutually exclusive. Instead, I think of it as (like you said) communicating the value effectively: dispense with the throat-clearing, meandering intros, irrelevant personal details, weak thesis statements, etc., and write tight, well-crafted prose that respects the time and honestly maintains the interest of those who'd benefit from the value you can provide. (I certainly don't claim to be an expert here! Appreciate the video link.)
