Of all the people who care about automation, if there were good, viable low-code options, developers themselves would want to use them!
Those tools are probably what killed the market for professional WYSIWYG editors.
It's worth noting that your point is correct: a no code solution for building websites is inevitably going to be limited in terms of how much customisation someone can do, but one gains speed and ease of use on the flipside.
The editor itself is ok but they've solved html/css by making gui for everything. You are writing html/css and you have to learn it. You just don't realize that. Apart from some animation/interaction there is not that much magic. Give it to someone with no html/css knowledge and you get "brute force" style of writing css where everything is inlined, absolutely positioned and has all possible breakpoints for everything. But i guess thats fine for the marketing pages.
