ESB also shows Yoda being a hermit, who meditates and lives peacefully away from civilization. The prequels show him as essentially a public school teacher for young children, living in the big city. It's a jarring inconsistency, and it just doesn't feel right.
Furthermore, ESB and ROTJ imply that the Rebellion doesn't know who Yoda is. As Senators in the Republic, the Rebel leaders would know about any Jedi who were prominant in the war.
