Such legislation isn't theoretical or difficult, India already has their new IT law rules:
>The IT rules 2021 provide for creating avenues for grievance redressal apart from Courts and ensure that the Constitutional rights of Indian citizens are not contravened by any Big-tech Platform by ensuring new accountability standards for SSMIs.
>During the extensive public consultations on the ITRules, the Minister of State for Electronics & Information Technology and Skill Development & Entrepreneurship, Shri Rajeev Chandrasekhar had articulated the stand of the Government that - safety and trust of every Digital Nagrik, and robust grievance redressal system to ensure accountability of all Internet platforms offering a service or product, was an unambiguous goal and that all grievances must be 100% addressed.
>The Grievance Appellate Committee (GAC) is a critical piece of overall policy and legal framework to ensure that Internet in India is Open, Safe & Trusted and Accountable. The need for GAC was created due to large numbers of grievances being left unaddressed or unsatisfactorily addressed by Internet Intermediaries. GAC is expected to create a culture of responsiveness amongst all Internet Platforms and Intermediaries towards their consumers.
