Amazon do pay people to contribute to the kernel, and they have their own Linux distribution which when you poke it looks an awful lot like RHEL/CentOS but different due to some things Amazon add/change, so I'm not sure that's the greatest example. Red Hat probably aren't thrilled about that situation, but in the same breath are a larger company and not under the same pressure to simply survive at this point.
