Inversely, I am convinced that is largely what has made Apple so successfully at the core, controlling the OS did not limit them to all the technical reasons that, e.g., windows OS based scrolling and the track pads were/are so horrible, resolution limitations, and inconsistent design and styling of the OS that subordinated the value or beauty of any hardware design to the OS level that users interacted with… subordination to Microsoft.
It’s essentially unconscionable that they likes of IBM, Dell, HP, etc did not get together and at the very least develop their own OS and also aggressively counter the de facto monopoly stranglehold of Windows on government, which then caused the domination among corporations.
Similarly unconscionable is also the European failure and subordination to the USA/Microsoft by not fostering at least an alternative to Windows that its corporations and governments can operate on. There has been nothing but talk and tiny little forays into adopting open source, but absolutely nothing that could even rise to being a real alternative to Windows or even MacOS.
