Do they have News that gets updated as the voice of the brand? That's a blog.
Do they have a portfolio of work that gets updated as the work of the brand? That's a blog.
What about case studies?
Any ongoing activity that's add to the site in a "social update" sort of way is effectively the blog.
That's been WP original idenity. As you noted, that's not a priority any more. Now tools like Shopify, WebFlow, etc *in the eyes of the market* have parity. And while Matt went all in on Gutenberg / Blocks there were already a number of page builders. Blocks is not gaining traction. It was a *horrible* product rollout.
So what's WP's and Automattic's identity now? Extortionist?? Certainly looks that way. Ugly but true.
