In his Governance model For the project, Google notes that while it encourages contributions from outside the operating system, it “guides the direction of Fuchsia and makes platform decisions related to Fuchsia.” It’s not unlike how Google dominates the Android ecosystem.
Developers who want to contribute to Fuchsia, which Google says is “designed to put security, update and performance first,” should register. They can download source code and “clone, compile and contribute” to the project. If the developers do not have a Fuchsia compatible device (the original Pixelbook is one of these systems), they can test the operating system with an emulator.
Google claims that the operating system is not ready for use in general product development or as a target for development. The company has not disclosed if or when it will brew fuchsia in commercial products, but at least for now, it’s clear that the project is still a real thing that’s definitely alive and hanging around.
