Often (usually?) it's not about money though.

Say you work at FB on unannounced project X. You want to integrate with open source component Y, from a FB open source project but you have questions about the right way to do it, and how to get needed features into the open source project.

You can't discuss this in public channels, and all the maintainers are right there available to you internally. So what do you do?
