Buddhism as a derivative of Vedanta

One of the biggest myths about the origins, growth, and spread of Buddhism is the fact that Buddhism was a revolt against Vedanta. Variants of this myth include characterizing this as a revolt against Brahminism and the corrupt Brahmin priestly class. To be fair, there is a grain of truth in the last bit about the corruption of the Brahmin priestly class but the originators of this myth are really hitting at Vedanta because they posit Buddhism as a philosophy that stands in opposition to Vedanta.
