Sounds a bit like a modern, open approach to the problems that were solved by QNX. Excited to see how it evolves!
Not really open. If you submit code, you grant a license to Google to use it in non-proprietary code.[1] So, at some point, once users and developers are locked in, Google can make later versions closed and proprietary enough to stop clones. Like they did to Android with Google Play Services. [1] https://cla.developers.google.com/about/google-individual
People said the same thing about Android in its early days. It was wrong then, still wrong now, and will likely be just as wrong in the future.
