If Obsidian weren't proprietary, I'd probably be excited for it. They do make it easy to jump ship, but I'm still both morally opposed and skeptical. If they really had your best interests at heart, they wouldn't keep any secrets. While the company appears not to be evil at the moment they could change their mind at any time, potentially without you knowing.

Instead I've chosen to replicate Obsidian's functionality in VSCodium. The parts that are missing (Mostly advanced search/scraping functionality) writing scripts to do. This works well because I've already modified almost every aspect for writing code. Extending it to notes should be relatively simple.
