>Nobody but Red Hat makes any money off the Linux kernel.

You forgot about Canonical.

But the real point is, in the wild, the Linux kernel predominates.

Every Android user is a Linux kernel user. Every Chromebook user is a Linux kernel user. Every iOS user is a Unix user. Every Google server is a Linux kernel installation.

The fact is, Linux/Unix rules. Except for the corporate desktop, where Windows predominates, at least for most (uninteresting) instances of "corporate".
