Your implication is that Google is not treating Fuchsia as a 'throw it over the wall' project, but as one with community participation. How many of your colleagues are from outside of Google? How often do you work with non-googlers as you develop it?

Are you regularly reviewing code submitted by your colleages at Samsung?

The fact that you're confused by the concept of working with people outside your company doesn't bode well for the open-sourceness of this project.

They're probably talking about things like Go where it's open source, but it's controlled by Google employees.
