That is really, really not the case. You don't pay for someone holding your hand. You pay for support because you either simply have the resources to do so or your business requires you to pay for the things you use.
If you need help setting up Kubernetes, glusterfs or something else you get help from a third party contractor. That's what we do.
You pay for support because your want someone to keep sending out security patches even if upstream should roll over, and you pay for Red Hat specifically because you want to have an upgrade schedule your business can adhere to (as opposed to when upstream feels like it).
Put another way, you pay for the privilege of having someone to sue.
