The most essential principle of the religious world is: "Use Torah to make money, but do not say that that is what you are doing." It is rare to find authentic Litvak yeshivas that learn Torah for its own sake and only accept money as a last resort in order to be able to learn Torah without interruptions.
It is not hard to tell the difference between the authentic Litvak yeshivas and the Sitra Achra yeshivas that use Torah to make make money or gain power and influence.
