Whats the point of Open Source?

What do you get for commiting to open source? You get reputation and coins on stackoverflow, but here you only get a green box in your commits history, is that all? Is there any work going on a similar reward system? 

Would YOU like there to be a reputation system? 

Well I think I can answer your question, look at spotify, it consumes more than 239 moving parts which are developed or began as open source.  This is very powerful.  You are using opensource software now, you just don’t know it, it has been corportised.
