Neither the Zapatistas or Rojava are anarchist. Decentralized and democratic, especially compared to their regions as a whole? Yes. Anarchist? No.The big obstacle to anarchist success in a lot of revolutions is that non-anarchist socialists and communists are more ready to use violence to suppress the anarchists than anarchists are to suppress more authoritarian communists. And that only intensifies when you consider right-wing factions like the Whites in Russia.
This is not to say anarchist revolts cannot succeed (Rojava and the Zapatistas say hi) but it's far harder when faced with a group like the Bolsheviks who were prepared to defend what they defined as a revolutionary society by any means necessary (and it gets worse with for instance fascist societies, though that's less relevant to Russia)).
