As I said before, I'm not a professional writer or debater. If anyone has any suggestions how the OP could be rephrased to make it more intelligible and perhaps less "controversial" I'd be more than happy to consider it.
Meantime, here are some sources if you're interested.
Marx lived for many years on money borrowed from others – I. Berlin, Karl Marx; S. Avineri, Karl Marx: Philosophy and Revolution
As shown by his private correspondence, Marx used even his middle-class associates (Freiligrath, Lassalle, Kugelmann, Engels and others) for financial as well as political ends. - Marx, K., Letter to Engels, 10 Dec. 1859, MECW, vol. 40, p. 547
By their own admission, Marx and Engels found value in the workers’ organisations they joined only to the extent that they could control and use them for their own purposes. - Berlin p 247
Marx chose philosophy as the instrument through which to change the world according to his own ideas, declaring that the purpose of philosophy was to change the world – Marx, Theses on Feuerbach
Marx was involved in funding arms for an uprising in Belgium – Jenny Marx in Jenny Marx oder die Suche nach dem Aufrechten Gang, p 57-8; F. Wheen, Karl Marx, p. 126-7
Marx advocated a coup to overthrow the government in Germany and seize power - Kolakowski p. 437; E. Bernstein, The Preconditions of Socialism, p. 152; Marx, Address to the Central Committee of the Communist League, May 1850
During their time as journalists, Marx and Engels learned how to use veiled, ambiguous and suggestive or misleading language to evade the political press censorship of the German state.
They used the same type of language to increase the appeal of their policies among existing or prospective followers - Adamiack
Marx and Engels used concepts and theories that were ambiguous, inconsistent or just nonsense – L. Kolakowski, Main Currents of Marxism
Marx was described along the lines of “liar and intriguer” by Karl Heinzen, Bakunin and others - Berlin
According to witnesses like Gustav Techow, chief of the general staff of the Palatinate Revolutionary Army whom Marx wanted to win over to his socialist movement, Marx’s intention was to drive the aristocracy from government and seize power for himself with the help of radicalized elements of the working class – Wheen p. 240
My summary of the above (and other data): You can't possibly spend years developing a political philosophy only to leave open all the central concepts related to its aim and purpose. Marx and Engels' "political philosophy" or ideology is logically inconsistent and ambiguous because it is meant to appeal to imagination and emotion without revealing the true intentions of its authors.
