Not sure that is correct, the companies contractually responsible for the nordstream 1 turbine maintenance/repair were European and Canadian, that were refusing to repair them because of the sanctions on Russia
Strangely, gas turbines supplying Hungary which showed a more friendly posture towards Russia didn't break all of a sudden... I obviously can't prove that the Russia controlled companies that operated this equipment deliberately broke anything but in the past outages like this were relatively rare.
