I have a feeling that "Russian BAD" camp is trying everything they can to come up with an excuse why this isn't true.
Could there be a better boat to do this? Yes.
Could there be a worse boat to do this? Also yes.
There is so much more we don't know, but I am still waiting for an explanation from aforementioned camp of why would Russians destroy an asset into that they invested a lot of money, that was bringing them hard currency they desperately need (this is somewhat of contested theory, since they seem to be doing fine so far) and was providing them with at least some leverage over EU countries that pipeline served.
Germany was reluctant at that time to cut off that particular supply and support Ukraine. All that was accomplished so far, if "Russia did it" theory is true, could have been done with simply turning some valves off. IIRC, there was some of it happening anyway. And from what I am hearing, German companies, and by extension German politicians, would be more than happy to get that back.
Not to mention that Russian gas company is still delivering gas to EU countries, so theory that they wanted a way out is simply not ture.
