> if Microsoft just re-enables those settings when you update windows?
That's another matter entirely. Microsoft's current strategy is to give at least some appearance of getting informed consent for those anti-features. Silently re-enabling them during an update without asking the user would be much more likely to get them in trouble.
It is not another thing. You argue that auto-hiding scroll bars are used by Microsoft to create dark patterns for hiding settings from you. My point is that the problem is Microsoft and not an auto-hiding scroll bar.
“Make it apparent when content is scrollable. Because scroll bars aren’t always visible, it can be helpful to make it obvious when content extends beyond the view. For example, displaying partial content at the edge of a view indicates that there’s more content in that direction. Although most people immediately try scrolling a view to discover if additional content is available, it’s considerate to draw their attention to it.”
