The work done on the pipeline in the last few hours reminds me of when the US blew up a gas pipeline in Siberia in the 1980s, using malware, but they say this time the damage was caused with explosives. My instinct is that this was not Russia, as many of the reasons being cooked up to give them motive seem somewhat desperate and implausible, but it took something like 20 years for Reagan's handiwork in Russia to come out, so don't hold your breath waiting for the mask to be pulled off the real culprits of Nord Stream.
