Well, english is not my first language, but according to Google (they get their word meanings from Oxford) “confirm” means “establish the truth or correctness of (something previously believed or suspected to be the case).” Perhaps in this specific situation “confirm” has different meaning?

Also, there is a lot wrong how science is communicated in popular media. Taking singular study, coming up with sensational (and incorrect) title and making statements that aren’t in line with the study is not the way how science should be communicated. Even if there are multiple news outlets writing numerous such articles doesn’t make it right, correct or even acceptable.
