No, it's called experience.
You know how much I deal with open source software? You know how much this problem occurs with that? Outside of making your software GPL so that others are forced into sharing their modifications to source code, people will try to close the door on others and keep things to themselves.
Then, when you try to ask them for their modifications, they basically tell you to forget right off. The problem with idea stealing is very real pretty much everywhere.
