Hey, I'm not saying the person has to like it, but they're complaining at length about an OS strictly because they are unfamiliar with it.
Also, sorry to disappoint you, but pressing Return has entered name-edit mode for files and folders since literally the very first Macintosh, running System 1.0. I just tried it. I'd love to hear the long list of GUI-based OSes from January 1984 (or earlier) that used Enter to open/execute the selected file/folder, though.
Yeah, we were talking about a graphical file manager, and selecting a file/folder/executable and pressing Return. Not the same as entering text commands in a CLI. I can see why you'd try to make this argument if you were conflating the two though. /shrug
Yes, every other OS on the planet, since the beginning of time. This is just Apple being weird for the sake of being weird.
