I think that being open to working with others is implicit in deciding to maintain a widely used project like Linux. There's tons of open source tools which are explicit "this is something you are free to use but I created it for my own purposes and don't intend to support it"; however, that isn't how Linux presents itself.

That is to say, if you are building an tool as a collaborative open source project, then that implies that you intend to collaborate.
