I see this as part of Google's upcoming effort to move vendors off Linux to their proprietary Fuchsia kernel.

(A certain alternative pronunciation of its name perhaps telegraphs its purpose.)

We may be heartened by the previously demonstrated inability of large organizations to create a viable new kernel from scratch--OS/360 excepted.

Even though it is often rendered moot by the fact most people use distro kernels, making it (slightly) harder to find the addresses of non-exported symbols is probably (slightly) raising the cost of producing, and testing, exploits reliable across a range of kernel versions, configs and patches from vendors. This is unlikely to be a bad thing, especially with most kernels lacking powerful anti-exploitation features.

Fuchsia is open source.

Upstream is at the moment. Given that it is permissive licensed and mobile vendors like to slap on a ton of patches for differentiation, how it will be distributed in practice is murky and the outlook isn't great given the track record even with current Android

The fuchsia license looks a lot like the 3-Clause BSD License. For some reason, reminds me of BSD - The Dark Horse of Open Source.

I have worked with packaging chromium for Debian before, and I also know that every time the v8 developers at Google do a refactor they do a Fuscia on IBM's work to port to POWER. If you are anti-social a "Do What The Fuck You Want License" is certainly not a promise not to fuck their users, especially when the users are NOT using an open source build.
