I think that user experience of website builders with wysiwyg and drag and drop UX won over time. Then, as time passed by, website builders become bloated and complex. Once again you needed a professional to maintain your site in site builder.
So now simple solutions, static HTML, free or one-time fee CMSs are sexy again. (economy is not good, who wants another subscription?)
I know because 14 years ago we have created static, drag and drop CMS that people still buy today. People value basic features. And it's hard to make a complex software that's easy to use.
Basic features are still enough, after 14 years. https://sitecake.com
