MacOS Tahoe has been heavily criticized for its UI decisions, especially Liquid Glass, which many people feel actively hurts usability rather than improving it. On the other side, Windows keeps piling on user-hostile features, dark patterns, and friction that increasingly frustrate power users and regular users alike.
Distributions like Ubuntu, Fedora, Mint, and others have mature desktops, solid performance, and fewer design decisions that get in the user’s way.
I honestly cannot remember another moment where both major desktop platforms were being questioned this openly at the same time. If Linux is ever going to take advantage of dissatisfaction at scale, this feels like it.
