Link: IBM Takes A Hands Off Approach With Red Hat

The reason for this hands-off attitude for such expensive acquisitions is simple: Both VMware and Red Hat live and die by the fact that they are neutral to any particular platform. While IBM may prefer Red Hat’s various elements of the stack – the Enterprise Linux operating system, the OpenShift container system, the OpenStack cloud controller, the JBoss application server, and the Ceph block and object storage – it cannot prevent Red Hat’s vast partner network from doing what they do, which is compete against IBM and each other selling Linux stacks. To not do so would be to destroy the value of the Red Hat business, just as Dell would destroy the value of the VMware business if it had only put VMware’s virtualization and cloud software on its own PowerEdge servers
