I used to ask this question back ~2015 - I was seeing companies with massive, clunky CMS installs just so their non-technical/less-technical staff could update their websites without filing tickets to IT/dev. It seemed to be more about those departments wanting autonomy and not having to wait weeks or months for internal IT/dev to make site updates. The consensus within one dev group was that the company would have been better served by hiring someone who knew HTML/CSS/Javascript to embed with the non-technical people and edit a straightforward frontend site for them.
