nah, Linus Torvalds wins. I really really doubt that Minix is more deployed than Linux... just think of three examples (and there are probably many more examples):
* Linux in all variants running in billions of VMs and Containers.
* Android.
* There are not only Intel chips out there.
So Kudos to Dr. Tanenbaum but adding all numbers I don't think we have Minix nearly as much deployed as Linux ;)
Fuchsia is open source [1] [2] though not specifically GPL. It uses a myriad of licenses.
> I wonder how/if that will impact the platforms popularity.
It won't. Vast majority of users don't care about open source, and developers won't have to care. The kernel and userland get replaced, but the underlying Android OS (excluding GApps) remains open source.
With both the kernel and userland being replaced what, exactly, do you consider the Android OS to consist of?
I assume you're referring to the Java based frameworks and Dalvik/ART runtime pieces, but I would usually consider those part of userland, and your comment is a little unclear.
