Title is confusing, OpenJDK does belong to Oracle and Google is going to use it. It's just that the OpenJDK is GPL.
TFA doesn't make much of this all that clear to me. Though I admit I only skimmed it.
Judging from the commits on AOSP, ART is still being worked on and has been adapted to openjdk.
It looks like it is here to stay.
I think they're pretty anti-GPL with Android, and have some rules against inclusion of GPLed components there, besides the kernel. I think the whole userspace is under non-copyleftish BSD/MIT/etc.

No.

OEMs don't want their hardware support to be GPL-encumbered. See https://source.android.com/source/licenses.html
