Serfs were freed in 1861[1]. A year before slaves were freed in the USA[2]. By Alexander II - the grandfather of the last Tsar.

Totally unsurprising, given that their "communist revolutions" were revolutions in name only, and happened in conditions Marx had spent decades explaining why would not lead to successful transitions to socialism, much less communism (first, as far as I know, in "The German Ideology", 1845, Part I, section A, 5: " And, on the other hand, this development of productive forces [...] is an absolutely necessary practical premise because without it want is merely made general, and with destitution the struggle for necessities and all the old filthy business would necessarily be reproduced").
Both the Bolsheviks and the CCP quickly re-established near feudal structures in response to opposition or failures - soon only the titles and names were different.
You're right though, this isn't really adequately presented in the article. Cybernetics is definitely worth investigating, though, for anyone doing big data today. So many lessons learned, forgotten, and re-learned, over and over again in the big ocean of human consciousness ..
In spite of being a free market supporter, I think that command economies have been useful at times, e.g. the PRC and the USSR in their early stages. Both these countries practiced something similar to what Chile tried, in the 70's and early 80's. My theory is that before communism these countries were practicing a a very corrupt state capitalism. So a logical step before capitalism, was to rationalize state capitalism by making government decisions based on utilitarian goals instead of corruption.
EDIT: modified my request for title change after I read the original title more carefully.
