You can't actually use reason to understand modern UX/UI designers choices. I've just got Windows 11 at work. They've increased the blank space between all the items in the file exporer quite significantly. They clearly don't care about vertical space because I know have to scroll first in places I could click first before.
Feel free to enlighten all of us, instead of using ad hominem on this particular comment. I, a lowly uninformed user, would love to know what UX/UI is versus what it pretends to be, so that I might understand the decisions being made in Windows 11.
