Their criticism is linked first, and about half of it lands
What they argue
That this consistently frames change as loss and does not distinguish between things worth mourning and things worth being glad about.
Where they are right
On the framing, entirely. Reading back, about two thirds of pieces use the vocabulary of loss without examining whether it applies.
Where I disagree
On the conclusion, that this makes it useless. Recording what went is worth doing even when the going was an improvement.
