Is it though? Nowadays you have plenty of good free CMS-es which integrate directly with Netlify. Sure, it might be half a centimeter more complex than WordPress admin but it's still really easy to grasp for many non-tech people (checked).
But even if it was very complex -- which it isn't -- I still fail to see how that supports a model of an ad-supported web hosting.
