If it is the fault of the Germans, then it is more so the fault of the Russians, but honestly if the Netherlands doesn't have natural gas, why be shocked when other people raise prices for a substance you can't do without and must buy at any price?
At least the Scottish have the argument that all things being equal they don't need Russian gas, so the only reason their prices are high is that if you've got a bunch of gas in Scotland, you should sell it all for $$$ to the Netherlands unless the price in Scotland rises too.
How is the Netherlands on Electricity? Are you like Scotland on that too, where despite notionally making most of your electricity without needing gas, the market clearing price is determined by gas generators and so it soars because gas prices are high?
