Earlier quoted context omitted.
I feel obligated to mention Logseq https://logseq.com/ as well as Zettlr https://www.zettlr.com/ which are both markdown editors with knowledge base and management. Incidentally, I do all of this in Emacs.
Here's the thing: I really like Loqseq's interface (it mimic's Andy Matuschak's Evergreen notes[0]) but I really hate the fact that it doesn't let me edit plain Markdown files and write free-form text. (Looks like I'm not the only one[1].) It forces me into this weird outliner format that I personally don't like at all – and I'm saying this as someone who used org-mode for years.

I think there are a lot of different styles out there which manifest in how different people end up using these tools.
I ended up moving from Obsidian to Logseq basically just to get "native outline format", and LogSeq is in that sense an "offline, open-format version of Roam".
