There is a very important fact that the Anglosphere (and the West in general) misses about India. We are a third world country where the State still has not acquired an absolute monopoly on violence. Most people do not trust that the cops will enforce the laws or that the courts will provide justice in time. Jurisprudence is all but non existent even at the highest levels and judgments depend on the whims and fancies of the judge/magistrate. This essentially results in a lot of disagreements being resolved in an extremely violent manner on the streets.
Under Articles 19(1) and 19(2) of the Indian Constitution, an individual's right to free speech is not absolute.[1] Further, Indian courts have often toed the line and held that maintenance of public order overrides any individual's right to free expression.
Political Twitter in India is primarily used by pro- and anti-Modi groups to abuse each other. Every photograph of a burning pyre and every apology from a media organization is another stick to beat the other with. Anti-Modi media might want to blame everything on the Kumbh and the elections, but this second wave has been noticeable since early/mid February and warnings were coming from states like Maharashtra, Punjab and Kerala. But the state and central governments didn't take these cases seriously till things got out of control. At one point, about 60+% of all new cases and deaths were coming from Maharashtra where there were no elections or Kumbh.
Personally speaking, this censorship is immaterial in the Indian context. If these tweets lead to rioting on the streets and a few people are murdered, that is just another day in India. The only thing I know for sure is that the people who will die are not the ones who tweet.
