In this case, I had asked some RH folks about it when the acquisition happened. There was a lot of bravado that IBM would leave it be. This is small in relative terms, but appears to be the first crack. Thus, I'm curious if it's a hot topic there.
You align software to where it works best. IBM is better suited to develop and sell Software Defined Storage than Red Hat.
I saw some people furious because of personal prejudices against IBM but many seem to be looking at this opportunistically.
