Except that Microsoft has been increasing openness in their OS bar the update system that was implemented because surveys showed that people would never update and that is a serious security issue. They then made 2 version of Windows and numerous ways to stop updates via a simple command line of one could pass thr very low skill bar to actually do this, thus your parents get the mandatory updates like the children they are and tech savy people can do whatever. Linux now comes in every windows 10 install as WSL and you can do anything you can with a normal linux. So it is correct to say that OSes for general use have become more customisable and open.
