^ IBM is incompetent and only exist because of wealthy corporatations paying politicians to have long intellectual property lifetimes. Not quite the case. Current mainframe users haven't migrated from it largely because the simplicity of scaling up, which means they can always buy a newer and more powerful machine when current one can no longer cope with the workload. I would expect it's much cheaper than migrate to other platforms in most if not all cases, considering the costs to develop and test the applications. They can get away with it as long as they can find someone to carry out the upgrade/maintenance work. But if IBM keeps footgunnig itself, it won't belong before those users have to jump the ship as no one can work on it any more.
