This is a great mistake the commentators have made. In the Gītā, God said "mā phaleṣu". Its meaning is: "Do not want the fruit." "Mā" means "do not want"; that is, the sense is: "As for the fruit, it is there; but to give it up, saying, 'I do not want it.'" If it meant "there is no right", as the commentators have written, Kṛṣṇa Paramātma would have had to say "na phaleṣu", would he not? "Na" means "there is not". By saying "na phaleṣu" in place of "mā phaleṣu", they have altered even the word of God. That is a grave offence.
