I don't really know much about it other than I've heard people say they don't like Leninists. But like...why? The worker soviets are literally councils that served essentially the same function as what council communists want, but with the party serving as a vector for that organization.
Also, Lenin frequently brings up the Paris Communé when discussing the soviet revolutionary model. He talks specifically about how the initial revolution creates a bourgeois state "without bourgeoisie" and eventually withers away into what you'd call council communism.
Like council communism is just the "higher stage" of communism (or the communist stage of socialism) right? The model exists under Leninist organization and the contradiction of Leninism is the political/bureaucratic elite that isn't the workers. The difference between this state and the bourgeois state is that its really fucking weak usually. Like think about the "fall of communism", it was easily toppled, but instead of getting council communism (which is what the workers would have done if left to their own devices) they reverted to capitalism due to massive intervention of the existing well armed and funded capitalist powers.
I've now read half of the article and will probably read the other half later today, but as of now I feel like it trivializes Rosa's contentions with Bolshevik policy. Of course that stems from material conditions, but everything does. And nobody could seriously claim Rosa opposed the Russian Revolution or something like that.
To avoid posting "out of context quotes" I highly encourage everybody to read Chapter 6 of The Russian Revolution, it is a very short read.
tbf, that pamphlet was written before she undertook her own revolution, thus before she had to actually face running it, after which she became much more authoritarian
