A few more reasons occur: Bolsheviks nationalized all foreign possessions in Russia (which were very substantial - foreigners owned 90% of the railways for instance). Also they appealed to the proletariat in the world and showed the potential of revolution to be real. Lastly they simply weren’t integrated with the western global financial and economic system. Really the source of the friction, more so than ideological reasons. For centuries before Russia was a virtual colony of the West, sort of like the third world today.
