It is true in most parts, not everyone is intrested in making his own game, like me. I am more intrested in looking into code to see how it is written how the certain parts works. Also open os semi open source is good to have people like me looking and giving possible fixes. Also you can share it private with me or any one that will ask you, so it will not be public, bus still you will be albe to have other eyes to look into bugs etc. I have rule, if something is given for free and I find a way to improve it I will share that across community, polserver.com is an example I am at that community for years and I share my ideas for free with them
