As the article states, for vaccinated people, the risk is low and the Delta variant is likely of little concern, especially when cases are as low as they've been since the start of the pandemic here in the US. However, it seems that the media is pushing the Delta variant as a narrative to help get people vaccinated but it's all falling on deaf ears of those who are specifically choosing not to get vaccinated. The stronger media coverage winds up making those who are vaccinated overly concerned about it, when they as protected as they will be from the variant.
For the unvaccinated countries and people, the Delta variant is definitely something to be concerned about. What we should be doing is trying to get vaccines rolled out to as many countries and people as possible, as that's our best tool for getting things under control.
