There's nothing wrong making this enterprise to be on par with other routes.
German corporations that collaborated gambled on getting unfair business advantage through geopolitics. They should loose. It doesn't matter they had political support of Germany initially. Political reality changed to the point German support of Russia can no longer be swept under a rug.
And with the despicable traitor not only to Germany but to Europe and arguably civilisation itself, ex-Chancellor Gerhard Schröder, fronting the whole enterprise.
