To us in the west, in particularly in the UK, this probably sounds like unacceptable censorship.
Just take a moment to think, while India is becoming a highly developed country, in the cities, and has an educated elite, there are huge tracts of the country populated by thousands of people who have not had an education, are extremely poor and where religion and caste is of more importance. They live in an environment that could be seen as medieval in comparison with the rest of the country. Suspicions and superstitions abound, people with a lack of education don't evaluate things as easily as an educated person.
It is no wonder that the Indian Government is trying to prevent these riots provoked by agent provocateurs.
It's not censorship per se, it's Governance and trying to establish a rule of law.
