Distinction between Intermediary Liability and Cyber Abetment: A Confusion Unraveled?

Yaar samajh nahi aaya... I'm stuck between IPC 505 and the IT Act's intermediary liability sections. In the context of online content, what's the difference between aiding the spread of fake news (IPC 505) and the intermediary being held liable for facilitating it (IT Act)? Can someone clarify how these concepts coexist or is one redundant? If I'm correct, IPC 505 is more focused on the creator of the fake news, while the IT Act holds the intermediary responsible. But what about section 79 of the IT Act, which says intermediaries aren't liable for user-generated content? How does this interact with IPC 505? Please help me untangle this mess for the Bar Exam.
