Hardik came under fire because of his lack of respect for women, this is 2019 and if you are misogynistic and then come in a national television show and say those things, you will get in trouble and that is what happened.
I could get why he was warned but this rule only applies to cricketers and not other celebrities. Anyways, I don't think Bumrah will get affected by it as he clarified that it was not transparent and was the effect of lights.
Coming to the match: Agarwal got out for just 16 runs. Looks like the decision was wrong and it wasn't reviewed.
