Easy page generators are definitely a good default which have enabled more people to create content (and not just recently, think myspace era and before) but the point wasn't "and it was better when you had to write HTML/CSS manually to have a page" rather "and these platform tools have started to elide the option to embed HTML/CSS when you want". This doesn't mean wanting to throw out the easy to use interfaces for a traditional CMS and writing everything out it means easy embeddability.

As an example think mediawiki and markdown. Each was designed to allow you to just make content, each has powerful GUI tools, and each was designed to allow direct embedding as needed. A lot of blog platforms have started to drop the latter bit for no gain in making the former bit more accessible than it would be otherwise.
