Found the fervent GNU worshipper.

Jokes aside, yes: Android is a Linux.

Just like how Xbox is Windows NT, and MacOS (and iOS?) is(/are?) BSD.

Unfortunately, when people call their os Linux, they typically are referring to its kernel. I wish there was a better term to distinguish Linux distros from the kernel.
