"Bringing in money" is the agenda not the integrity of the game and not calling the games in a constant fashion. Games are called wildly different even from quarter to quarter- see finals 2010 for reference.
Yes, you'll be shocked to know that "bringing in money" is the agenda of every for-profit organization. That is, in general, how the world works.
And no, the games are not called in a constant fashion, seeing that they're not called by robots. You know what else is wildly different from quarter to quarter? The production of your favorite players and Tommy's energy level.
I keep wondering why people who think the NBA is fixed keep watching games. But then again, some people watch pro wrestling, so what do I know.
