Fuchsia has a lot of good features technically, there is no doubt about that - it was time to revisit how an OS should be designed given the usage patterns of devices it powers. I hope the capability model will put to rest the insanity that is SELinux (just look at the amount and complexity of SELinux rules in AOSP). The license choice for the kernel is more controversial, but no one expected Google to ship under the GPL.

It also happens to solve some of the pain points with Android: in a way it is "Project Treble on steroids" aiming to resolve the issue with fragmentation and lack of long term support from Android chipsets and OEMs.
