Link just means correlation. Correlations are easy to find and don't mean much.

They don't explain why and how dairy would help reduce risks of diabetes and high blood pressure. So they're not doing science.

Note how they say:

> This is an observational study, and as such can't establish cause.

It's not like you could ever establish a cause anyway. Causes are explanations and they are conjectural in nature. They could have just guessed that dairy helps reduce those risks and then try to explain why. That data from all those different countries could then maybe be used to refute that explanation. But the explanation should come first.
