Is Section 79 of IT Act a Get Out of Jail Free Card?

Main issue yahaan hai ki Section 79 kahaan keh raha hai ki third-party liability nahin hoti hai jab koi online content upload karta hai, lekin Section 66A keh raha hai ki third-party liability hoti hai jab koi objectionable content upload karta hai. To aise hain yeh kya, main confused hoon. Abhi tak koi book hai jo is cheez ko explain karne ka? Kiska koi tola hai yeh doctrine? Aur iske liye kya procedure hai? Section 79 khaali hai ya hai ismein kuch specific karna padta hai? Pls help!
