What if ISRO worked with SpaceX

Why is only Space X making every phase of the rocket launch open to the public?

I don't think it has much to do with convincing NASA or other potential customers. Eventually, they will get more information directly from SpaceX than you can get by watching a video of the launch, and they will know how a launch went even without the video stream of the launch.

No, I think it has more to do with Musk's personality in general and her ultimate goal of getting to Mars. In order to get a colony up and running on Mars, a few things are required. One way to get there and enough people who want and can afford it. SpaceX is trying to find a way to get there and make it cheap enough that people can actually afford it. So if they achieve both, all you need is people who want to leave. If you get people excited about space now, you can find people who in 5/10/15/20 years or whenever they actually want to get BFR to Mars.

I'm sure some people would say that Musk is a dog of fame or loves the lime light, but I don't think that's actually the case. I think he just really believes in what he's doing and is excited so he wants to share his excitement. I know it rekindled my excitement about space and upset my son about it. He built his own FH out of Legos after seeing the launch, but was a little disappointed that there was no RUD.

When I talk about this, I would totally believe that his intention was to use television to inspire these things - especially with his payload choice of a Telsa roadster. But I believe this and the other answer have been merged to be more specific. He saw both the benefit of inspiration and the benefit of exposure, which is a win-win situation.
