I did not say the copying is wrong. I said copying is not innovation

I think you might be unfamiliar with 'open source' and its licensing. Android is a Linux-based distribution, which means that it uses a Linux kernel.

'Copy': make a similar or identical version of; reproduce: [1] Google forked and contribute to the kernel. They did not create their own identical version of, or reproduce, the kernel.

"Forking" does not necessarily mean "innovation". Innovation, by definition, requires something new. "Doing the same things differently" is only innovative to the extent that things are done differently. (Android certainly did do some innovative things, just saying that forking the kernel was probably not it.)

Yes, but reinventing the wheel is not innovation, it is stupidity. Why write a new kernel if there is a very good one available? Innovation often is in taking existing things and combining them in new ways (or improving already existing inventions, which is what google is doing).

but, but, but, I never mentioned anything about forking === innovation (unless your response wasn't directed at me :) ).
