A common misunderstanding with this hadith is what the man means, and more importantly, what the man does not mean. The man is saying he will pray but only the obligatory prayers, give the mandatory charity (zakat), only fast during Ramadan, and make Hajj once; and it is in these actions that he will neither increase nor decrease. The man does not mean he will backbite, oppress people, abandon those who need help, and keep sinning while performing the minimum actions. He is still obligated to behave properly, fulfill his responsibilities and keep away from sinning.
