What's not clear to me is who will be held responsible on the part of Twitter for any complaints. Earlier, Twitter had provided a local contact, which was that of a lawyer, as the contact for complaints and grievance redressal. That wasn't sufficient since the lawyer was not an employee of Twitter (as required by the new rules). He also left that position soon after. Twitter India has a managing director (MD), Manish Maheshwari, who claimed recently that he was only managing the marketing side and is not responsible for content moderation or anything else that happens on the platform. He was also granted a stay by the Karnataka High Court (which is where Bengaluru/Bangalore is) from arrest in a case filed in another state in the north (UP, i.e., Uttar Pradesh). [1]
I personally don't think Twitter India will find people taking up the positions of Resident Grievance Officer, Nodal Officer and Chief Compliance Officer. These are currently open positions on the Twitter careers page. [2] Whoever takes these up could end up in jail, which could really be bad with a draconian law like UAPA (Unlawful Activities Prevention Act) that allows people to be (arbitrarily) detained without recourse for very long durations. [3]
The new IT rules have also been challenged in court on a few different fronts. "Two of the government’s own legal advisers warned it that the new Information Technology (IT) Rules were beyond the scope of the law and required parliamentary approval." [4]
