For example, if people were getting hacked through remote desktop connection all the time you could have said that macOS has insensible defaults on the security or even existence of that feature.
However, with macOS that's not the case, in fact macOS has so sensible defaults that a lot of its users have no understanding of how it works and yet successfully use it for years with no issues and not gaining any understanding through the years.
The thing is so well designed that it's often dissed as a Starbucks machine, implying that it is used by people with a lot of money who don't know what they are doing while simultaneously is an extremely popular machine among creative professionals and engineers who also like coffee and know what they are doing.
Having options is nice, for example I dislike dark mode but I like the dark statusbar so I have a customisation for it. I dislike autosorting of the Spaces, so I disabled it. I prefer to simply tap and not have to press on the trackbar so I enabled it.
However I would't call the defaults not-sensible, it's just that I like some stuff differently from the defaults.
