You are overstating the opposition. Kropotkin was generally friendly with Lenin and met with him shortly before their deaths where they were quite cordial though they disagreed, and he did return to the Russia while it was ruled by the bolsheviks.
While he did think the Bolsheviks would not achieve communism because of the over-centralization of their rule, he still supported their goals and thought the October revolution was worthwhile despite being bound to fail even if only as an experiment on how to better introduce communism.
Kropotkin was thus both an anarchist and a communist and was cordial and cooperated with authoritarian communists.
