I think the problem with the vi/vim example is that it's very much not for everyone. I use it, and have used it for 25-odd years, but I'm not an expert at it by any means (because I haven't taken the time to try to be), and occasionally have to look up how to do something. But I've customized it to my heart's content, and feel very productive in it. But I would not expect a large percentage of developers to want to do that. I've used IDEs as well, and they're mostly fine, and work really well for lots of people. Many IDEs are pretty damn customizeable too, though most people may not change many settings.
