It's a "the worst choice, except for every other choice" sort of thing.

WYSIWYG almost always generates nonsense in the underlying code, which can be very difficult to work with when it comes time to style that code. And since I'm a frontend guy, this is something I'm always having to debug.

The problem there is having to manually maintain code. Once we start abandoning useful technology to maintain the status quo, we don't get progress

I think people wouldn't prefer it if they actually knew something different. Non-tech people don't even know there's a world outside MS Office suite of tools, which shove you to WYSIWYG by design. From experience when showing somebody LaTeX, it's an eye opener people didn't know existed.
