Most were some degree of socialist/fascist.
When you can only open your business with a royal charter, that is not capitalist. When you can be forced off your property by the government so they can give it to someone else that is not capitalism.
The goal of the Bolsheviks in Russia was never to over throw "capitalism". How do you over throw something that does not exist? It was to put themselves at the top of the feudal/socialism system that was already there and take it even further back to the days of direct serfdom and slavery.
The Frankfurt School (German: Frankfurter Schule) is a school of social theory and philosophy associated in part with the Institute for Social Research at the Goethe University Frankfurt. Founded during the interwar period, the School consisted of dissidents who felt at home in none of the existent capitalist, fascist, or communist systems of the time. Many of these theorists believed that traditional theory could not adequately explain the turbulent and unexpected development of capitalist societies in the twentieth century. Critical of both capitalism and Soviet socialism, their writings pointed to the possibility of an alternative path to social development.
