And then Russia refused to install the turbine, proving it was a ploy all along. Like the maintenance in the first place. Which is why they acquired gas storage in Germany, then ran it low timed with their illegal war of aggression. This is a theme of course; Russia invented another gas crisis every few years with Ukraine. It should have been a warning sign when they settled them by taking payment in the form of Soviet-era cruise missiles.

The gas was never cheap, either; apart from the money spent now to restrain the military buildup and invasion it financed, even at the height of supplies it was much higher price than China is paying, a price sustained by Russia using military force and more to restrain other (Asian) countries from supplying to Europe.

(This was obvious to everyone, right? A single majority supplier nation state charging a cheap price out of the kindness of their heart? No, of course not; neither cheap nor kind. It was a monopoly, built on blood.)

They installed it and then they took the pipeline down for planned maintenance.

it's a little rich to accuse them of playing games with gas after the stunt Canada pulled and most especially after a western partner subsequently blew up the pipeline and blamed it on Russia.

Clearly certain western allies decided that Germany couldnt be trusted to make its own decisions about where Germany gets its energy.
