Links are "DOI NOT FOUND". Article does not seem to suggest that the study actual found any relationship between the increase in the two things, just that they both happened around the same time.
Unfortunately, even for the most fast-moving journals, that time is typically several hours before the actual articles appear on the journal’s website. So, anyone who’s reading quickly is likely to find that the DOI fails.
But that rule only applies to the fast-moving journals, like Nature and Science. Many other journals can take a few days between when they allow journalists to write about a paper and when it becomes available to the scientific community—PNAS, which is a major source of material for us, falls in that category.
