Huh? You're not confined to Automattic or WP-Engine, there are tons and tons of regular web hosting providers with Wordpress and a bunch of other stuff included in a standard hosting package, you can use the free Wordpress, and you can self-host. That's the whole point of Wordpress being open source, and it's working as intended.
There's absolutely nothing wrong with the status quo around blogging.
Static site generators are used by technologists who want to tinker and check all the boxes in whatever Chrome's latest devtool benchmark tool is called. Which is fine too, good for you if that's what you like to do with your time! For "normies" (or SME's who just want to publish their web content and move on), there are more than enough options around.
