Well, striking an agreement so that RHEL can run on the Azure Cloud
(where SLES and Ubuntu and CentOS are already at) and on hyperv .. and
working with them to make Windows run better on KVM as a VM to me makes
perfect sense.  Other linux versions are already there (hyperv/azure)
and their customers want a paid RHEL option .. and people also need to
run Windows server for some things as a VM on RHEL KVM hosts.

I certainly don't want to start a flame war either way, but people with
customers need to do what their customers want .. and on both sides that
was for things to work together in their enterprise from both companies.

Of course, we can start a flame war and discuss how evil Microsoft is or
how evil money is or how evil global warming is or any other number of
things.  There will be many people on either side of all of those
positions .. but I'm not sure this is the forum for those discussions.

The bottom line for DNF, just like any other software that Red Hat
releases is .. if they build it and make it the default in RHEL, it will
become the default in CentOS .. we don't political or linux religious
wars (like systemd, selinux) here.  We build whatever source code Red
Hat releases when they release it.  Nothing more and nothing less.
