https://www.youtube.com/watch?v=IxqrSXiRja4, 6:37 starts discussion about integration, so you can judge exactly what he says.
"The only one we have not fully fully integrated yet, and I will emphasize the "yet" is RedHat".
"on the go to market side, I really believe in full integration".
you already mentioned the engineering teams, and I do think your framing is mostly right. However, I think it unrealistic to say I am going to fully integrate back-office, fully integrate GTM, and somehow engineering is totally untouched.
Right now operations is employed by IBM but still mostly working as they did at Red Hat. We'll see how that changes over the next couple years, as that would be the first look at Red Hat integrating into IBM.
