During the hundred year's war, Étienne Marcel did not recognize Charles V as a king and led an opposing power in Paris. Given that Charles V managed to settle his legitimacy later, how come France named a street and a metro after him, and even has a statue of him? Since he lost, I would have expected him to be considered as a betrayer.
The street was created in the second half of the 19th century, the métro opened in 1908 and the statue is from 1888. Also, there is a street Étienne Marcel in Tours. So even if he was a hero in Paris at that time, that's a lot of recognition from France, more than five hundred years after his death.
