A notes app that only works with one 2-trillion-dollar company's hardware and does not have builtin functionality to export notes (e.g. a menu option to do so) cannot reasonably be described as good. One's expectations have to be through the floor for that to be an honest appraisal.
Compare it to Obsidian, which just stores data in a bunch of markdown files on disk.
I don't actually care about getting some data dump out of Notes. I use it as a way to quickly store temporary information. Any note older than a month is most likely useless. The most important feature is that it effortlessly syncs between my phone, work laptop, and home laptop. And that it does. Unlike a bunch of markdown files on disk where you have to create some janky syncing setup yourself which has no conflict resolution system.
No goal posts move when the original issue is not resolved with the proposed solution
Like, without any menu you can export your notes to a screenshot, but you wouldn't accept it as an export option, would you?
Similarly, PDF is an awful format for notes, so the fact that it exists doesn't solve the issue that you can't export your notes (which at a minimum you need to be able to do in batches, not individual notes)
Most users interpret "Export" as an operation that lossily finalizes a project from its native representation to a common third-party format. "Export" is one-way, "Save As" is bidirectional.
- Audacity "Saves" audio projects to its native .aup, but can "Export" them to .mp3 or .wav
- Photoshop "Saves" .psd files, but "Exports" them to .jpeg
- Gimp "Saves" an .xcf, but "Exports" to .png
- Apple Notes "Saves" notes to its own sqlite database, but "Exports" to txt or pdf via a menu item
This technically satisfies your comment above, which is why we speak of moved goalposts.
It would be great if apple notes could convert your note library to ENEX or a .zip file of HTML items.
