It is a meaningless buzzword, and has taken on an almost doublespeak connotation.
Remember when Windows let you adjust the sizes, colours, and fonts of every single UI element? Windows 3.x had that.
They removed that 3 versions back (Win8).
Then they removed some more in Windows 10, and in Windows 11, even stopped you from moving the taskbar to a different edge of the screen; and then, they have the gall to say it's "most inclusively designed".
Well, I can't comment on their effectiveness in having made the operating system more accessible since I haven't (properly) used it in a decade and a half and I'm not disabled, I'm just saying the phrase does have meaning, and relevance to usability, as they used it. Whether their description is accurate is another question
