How do you see the similarity between the ideas of the 13th century heretics and the sermons of Jan Hus?

The views of the 13th century heretics, the Albigensians and Cathars of Provence, and the sermons of the Czech priest and dean of the University of Prague, united a dislike for the clergy, who were mired in corruption, for the papacy and the official church, which became greedy, depraved and corrupt (indulgences and simony). Hus believed that both ordinary people and priests have the right to receive communion in the same way, since everyone is equal in the face of God. Priest Jan Hus and the heretics found their death during the Crusades and at the fires of the Inquisition.
