couldn't agree more with the section about Ghost, their shifted focus is something I've picked up on recently too [0]. I started to dislike their interface more and more when creating/editing posts.
Couple that with the regular "your theme is no longer supported" messages, I got fed up of burning time to keep up with their updates, which offered no benefits to me. I quit and moved to Hugo (using a ghost-to-hugo migration tool [1]).
