In this case the "closed source app" is using a very open and easy to parse format.

If Obsidian enshittified tonight so badly I had to stop using it, the only thing I'd kind of miss is dataview and bases.

And of those dataview is "just" parsing a bunch of markdown with javascript. Bases is a yaml format for displaying more markdown.

I'm pretty sure I could vibe-code some scripts over a weekend that cover most of my Obsidian use-cases and use any markdown-capable editor for writing.

That's why I use Obsidian (and stopped using Joplin, because - at the time - all my notes were in one obscure blob)

Same here. I have not found any open source option that does all of these: Nice user interface / App for both Mac and iOS / Automatic syncing.
