It isn't that Office is abusive or Windows is abusive, it's that Microsoft is.
Word '97 is still my favorite word processor ever. Windows 7 is one of my favorite operating systems. I don't think they're abusive.
What's abusive is how slow Office 365 is. What's abusive is how updates reset all my settings trying to make Office 365 bearable (don't use cloud, save to computer by default, don't show backstage, etc.). What's abusive is FORCING me to combine taskbar buttons on Windows 11. What's abusive (and unreliable) is randomly selecting the whole filename while I'm editing it when the file is on OneDrive.
unreliable software combined with abusive business practices
