Firstly humans having lizard brains is pop science nonsense, and secondly humans and lizards are amniotes. And thirdly, the Android userland is Apache 2.0 licensed, regardless of whatever proprietary apps might or might not be installed on top of it, and the vast majority of Linux distros’ kernels have proprietary binary blob drivers installed in them.
Windows is always going to be proprietary software, so I’m never going to give it the time of day.
Next question.
