I have a difficult time believing this. While I agree that Windows has definitely shit the bed and has been on a consistent downward spiral ever since they moved past Windows 7, I am also aware of the fact that organizations have a I can't think of the specific word for it they just have this organizational slothiness, an inability to innovate or change that is deeply ingrained into their structure.
Organizations treat software like concrete. You set it in place and then you never ever change it again until it completely crumbles and has to be drilled out with a jackhammer.
Even if every single person in the organization can you use Apple products or Linux products with perfect alacrity and competence, there are people who will not change unless they are forced to change and the force needed to make that change is just as large as the force needed for them to quit their current positions and go and work for someone else that is not changing.
The only way for this level of change to happen will be for an entirely new system to come into place that is easier to implement than maintaining the current system, and being as that many large industries still use 50 year old software I don't see that happening.
