I did not know who he was before the show so no bias beforehand.
From what I have seen it has been negative so far for Sidharth and the channel does not hide it.
The show obviously favouring him is making people more angry and accusing the channel of being bias.
I do not think the producers are stupid. They have found this to attract viewers and running with it.
They could have easily edited the show to make Sidharth pleasant and him winning would be met with cheers from many.
They have not. We should question this.
