I've no problem with using LibreOffice for most of my document needs, but i haven't found a good substitute for microsoft's OneNote yet. I mainly use it to plan my RPG games and it helps a lot. What alternatives are there for organizing notes on linux, with similar features to those that OneNote provides?
I wasn't worried about it being proprietary until I saw the founder reasoning for not having the source be open under a nonpermissive licence.

I decided to go with logseq because of it.
It also syncs with all my devices using my own servers, instead of needing to trust obsidian/logseq.
That's fair, the privacy concerns are not ultimately addressable with a closed-source application. I can encrypt communication and the db itself since I am self-hosting it, but ultimately I'm using the obsidian app on desktop and mobile so I don't know where the data is going unless I specifically manage it's network usage etc which is a ton of extra work.
I haven't actually started taking notes with obsidian yet, I just got it setup. But the plugin support is…massive. IDK.
