Vitamin D is a very inconclusive topic. That is why it is contentious. Go search pubmed or litcovid, there’s plenty of research.
I’m just calling out the fact that your complaint is not rooted in reality.
The studies you refer to are observational tracking people who supplement vitamin D or live in places where they get it naturally more. To say vitamin D is the cure to most things or even long covid is shortsighted and frankly irresponsible. Linus Pauling did that with vitamin C and tainted public opinion on vitamins.
