Its a pay per view for the broadcasters in the form of subscriptions. While I don't support this kind of activity I can see the damages done to a business if they are robbed of their audience. Broadcasters pay to have the show on their channel, why should they not be bothered when they are about to lose potential numbers because people have already seen the show before they air it? Viewers count is very important in this business.

Of course, they might have grounds to sue the leaker, but the fact that the police are interceding on the side of the broadcaster is what I find disturbing.

the police are involved because they have been asked to be involved. Do you think police only act on their own all the time? They provide a service and this one involves people violating law

Yes, laws. Is leaking an episode of a TV show a crime in Inida? Seems crazy.

The ideal of the justice system is to, well, maintain justice. Seems in practice they are, as you said, a service, a private goon squad for the rich.
