This requires a huge correlation != causation flag.

The article briefly mentions this, noting that it’s possible vitamin D is just a sign of a healthy person, so of course they’ll do better with COVID. Another correlation that doesn’t get discussed whenever vitamin D comes up is that people with darker skin generally have less vitamin D, because our skin doesn’t absorb sunlight as much. We also know that COVID is disproportionately hitting colored neighborhoods in the US. Is that just because of vitamin D differences? Who knows!

By the way, if you are a person of color, you probably need vitamin D supplements. The recommended doses are for white people, so adjust accordingly.

I felt like the article spent sufficient time on the idea that the explanation could be that healthier people simply have higher vitamin D levels, and that the vitamin D itself is not the cause. At no point did they choose a side on that part, the bias was only that they believe vitamin D is a promising avenue.

I really loved that the whole piece was informational, and not trying to convince the reader that Vitamin D is or isn't a cure or remedy for anything. It simply presented the available facts, the research, and the positives and negatives of that research. It even explained multiple aspects and positions of the debate on whether vitamin D supplementation is good or bad.
