Sure, it'd be nice to hold your government accountable. But when your ruler is effectively a tyrant in a government that is laughably calling itself a democracy, I'd rather have twitter provide its own opinion as well. Because at the end of the day you as the reader can still decide to ignore twitter's judgment and just read the document as you could before. It's additional information, not censorship - whereas the government wants to limit information.
Nobody is forcing you to trust twitter any more than they're forcing you to trust the government. You can ignore twitter's label and still try to hold the Indian government accountable - it's a non sequitur.
