A Spiegel article from september 28, two days after the incident: https://www.spiegel.de/ausland/nord-stream-spekulationen-ueb...
It links to a Times article allegedly saying the same (but behind a paywall unfortunately, so I can't check): https://www.thetimes.co.uk/article/russia-probably-bombed-no...
They're simply going for views and readers. The exciting story back in September was that Russia had sabotaged the pipeline. It was then more or less established that they probably did, so now the exciting story is that they might not have!
Other outlets seem to be commenting a bit more neutral: https://www.stern.de/politik/ausland/nord-stream-2--usa-soll...
