Sure, if the only thing that matters is the Linux kernel.

That is exactly what I said. Notice the rest of the desktop components do not share this allergy to gplv3 linux itself has.

Those desktop components are irrelevant in Android and ChromeOS.

This is not entirely true; as I argue on another thread, ChromeOS is much closer to desktop Linux than Android is. Anyway, this is orthogonal to the above point.
