Linus Torvalds. But what does he know, eh?

Most likely he doesn't know, as he isn't a phone OEM.

In reality pretty much no Android phone runs a stock upstream Linux. They all have horrible proprietary modified kernels.

So no, Android isn't even Linux in the narrow technical sense of the kernel it runs.

(The Android userland, of course, is an entirely different OS that has nothing at all whatsoever to do with Linux or any other flavor of UNIX, current or historical.)

At what % would it no longer be Linux ? What happens when they backport fixes from upstream for certain problems ?

> At what % would it no longer be Linux ?

Wrong question. Android phones run proprietary kernels. So by definition they aren't Linux, even if technically the largest parts of their codebase are taken from the Linux source tree. (Yes, all Android phones technically violate the GPL; in spirit if not in letter of the law. Unfortunately that ship sailed long, long ago.)

Wrong assumption,

License is not the same as code base. Violating a license doesn't stop something being what it is.

The uname -a will disagree.

oh then Internet Explorer is Mozilla because of the User-Agent string

Your analogy is faulty because one is lying about its origin of source.

Username remarkably relevant. Clever troll account. Well played.
