The reality is many people struggle using WordPress for anything more advanced than writing

THAT, folks, is a blog-centric perspective.

The 'reality is,' out of the box, WordPress is JUST a blog platform with the ability to easily add pages. If what you want is a blog, it's pretty much good to go, and with the customizer, most themes are fairly easy to tweak even for non-techs.

To meet the specific requirements of specific businesses (like a CMS must), however, usually requires significant customization of UI, post types, custom fields, and templates, just to start with. Those customizations are hung on a reasonably stable platform (so far).

When proposed changes to the platform threaten existing customizations and the people working on the changes brush aside our criticisms as though 'we don't get it', expect the criticisms to grow increasingly negative.
