Perhaps that's the leading theory on 4chan or wherever you get your news from, but none of the mainstream western media suggests anything of the sort. In fact, the latest western theory is actually that Ukraine did it:

The European intelligence made clear that the would-be attackers were not rogue operatives. All those involved reported directly to Gen. Valery Zaluzhny, Ukraine’s highest-ranking military officer, who was put in charge so that the nation’s president, Volodymyr Zelensky, wouldn’t know about the operation, the intelligence report said..

Thanks for letting me know that there is no point continuing this discussion since I'm talking to a conspiracy theorist as opposed to a rational and informed person.

A basic search debunks a lot of what is in that article

They further cited a named lieutenant commander of the Danish navy and analyst at the Royal Danish Defence College for several reasons why it is not credible that such a small vessel was used for the sabotage. The force of the explosion and the widely dispersed debris implies that several hundreds of kilograms of explosives were used, an amount that is impractical to transport with such a small sailboat. Secondly, it is surprising that traces of explosives were found on the yacht, since in this case clearly no homemade explosive device was used. Thirdly, accurately placing the explosives on the bottom above the pipeline at 60–80 meters depth from a small surface vessel is practically impossible. The skepticism was shared by a named former chief analyst of the Danish Defence Intelligence Service now senior analyst in the Danish think tank Europa. The naval officer instead speculated that a submarine was used to place the explosives and pointed out that a sonar-equipped submarine can, with relative ease, accurately place a naval bottom mine with 500 kg of explosives.

Oh well here's an NYT article that says the same thing https://www.nytimes.com/2023/03/07/us/politics/nord-stream-pipeline-sabotage-ukraine.html

Not sure how linking to an old wikipedia article is "debunking" anything. And of course, the account from Seymour Hersh is likely what's really happened given that it's the only detailed and consistent account https://scheerpost.com/2023/04/05/seymour-hersh-the-nord-stream-ghost-ship/

US is the only country with the means and the motive to blow up the pipeline, and the fact that European countries refuse to publish the results of the investigation citing security concerns pretty clearly shows they know who did this. If it was Russia then these results would've been published long ago.
