Redhat isn't going to save IBM. They sold because they had an unsustainable business, and Openshift is still a risky play to run a stable business on. The container space is starting to get awfully crowded, and cloud providers can provide better tailored experiences and skip containers altogether with serverless.
As a long time taker of Redhat certs, I hope they pull through and still look something like the Redhat I have loved and known.
