Because I think quality of presentation is not being factored into the assessments you're seeing on that wiki.
I tend to recommend Healthline to the public because it clearly targets a lay audience, and chooses to meet that audience where they live. It's written the way I talk to my patients, and the information is accurate and accessibly easier to read.
Just look at the difference between the pages on hypertension from Healthline and MedlinePlus:
https://www.healthline.com/health/high-blood-pressure-hypertension
https://medlineplus.gov/highbloodpressure.html
The details and accuracy of the information is not different. But the way Healthline presents it is so much more accessible.
This is not something I had ever thought about before and I am also fascinated.
