Here, Kamra is not just stating his experience or opinion, but also instigating others. He is infamous for what he has done in the past (and is still fond of doing it). People don't need Kamra to complain and fix things on their behalf. If we don't like a service, we simply stop using it. But no one goes online and creates a mass movement unless it's actually harming someone.
In the same way, Bhavish also stated facts about Kamra, which are just as true as Kamra's experience with Ola. So, what's the harm? 😂
If someone is accustomed to insulting others, they should also be accustomed to bearing insults.
