But to accept this principle to have to also accept that some people will take your code and use it in ways that you don't approve. The hope/belief is that the good will float to the top. If you don't accept this premise then you don't really have an open-source project.

I can't figure out why Android open sources its code, ever. They don't seem to care about contributions from the community, and they obviously don't want people using their code in ways they disapprove of. It seems that the major reason for open sourcing their code must be something else. What I keep coming back to is that it somehow protects them (in most cases) of patent violations.

I've asked this in the past: what is Andy Rubin's open-source credentials? What open-source projects has he been involved in during his long and successful career?
