I think no one cares because basing your energy policy on buying gas from Russia is such an obviously stupid idea that no one wants to bring it up.

Russia is not your ally, Russia isn't even a reliable neutral party. Russia is explicitly the enemy of Europe and when Germans get that into their heads things will be a lot simpler.

It should not have been built in the first place. That's where the billions were wasted. A strategical mistake.

bc the natural question after that would be "why do you care so much? Do you support russia? Do you want to pay money to the Russia's war machine?" And tbh these questions are somewhat valid. The NS blowing was a signal for germany to reorient it's dependency on other re-sources, be that from US liquified gas, or gas pipes from norway, or buy nuclear from france, or buy solar panels from china

What do you mean? For months there were many long detailed news articles and segments, government inquiries, international cooperation between the Baltic states, Denmark, and Sweden. They are still ongoing. Scientists are still monitoring how much gas dissolved in the waters as we write this.

Previously when it was built, the environmental lobby was raging mad that it got green-lit (and even the military leadership sort of opposed it by saying that "it affects our security") but the commercial interests and ruling parties allowed it to go through anyway.

I think it was a Russian operation, it makes most sense to me that they would try to deprive Europe of gas and make Europe war-weary to stop supporting Ukraine sooner. But at the same time I would not be very surprised that a small group of Ukrainian operatives (as rumoured) did it to deprive Russia of income from the gas line.
