@LukeAlmighty One thing I've noticed that most people are very particular about is that they get to keep their programs. They don't want to learn some equivalent to, say, Excel. It must actually be Excel. There can be no comparison. And in their mind, any difference between Excel and whatever equivalent there is, is a flaw.

Windows is the correct path you see, and any deviation from that is by definition a flaw. You can replace Windows with whatever normie equivalent we're talking about in computing. A commercial streaming service for music that competes with Spotify we'll need to work exactly like Spotify in order to merit consideration. Even the slightest user experience difference will be considered a faux pas
