I've been using Apple since IIe in the 80s and all of the UI iterations. People make iOSification comments about macOS, and there have definitely been annoyances as they are seemingly trying to unify the UX. Maybe it'll make sense when they have touch controllable macOS systems, but making things that work well for fingertips and assuming they will work equally as well operating by a mouse is just bad.

As for Linux, I don't think I've ever used a system with UI for any serious amount of time. >99.999% of my usage is on headless systems through a terminal. As god intended.
