Omnivore is open source, bit weird people insist on open source because 'future proof' and then when the commercial entity disappears, it's 'dead'. Why do people make their own instead of making an entity around what is already there if it was liked and open? Very much a validation for not open sourcing anyway. But then again, I cannot possibly use Obsidian or so because when they sell the place (not if, when), sure I have the open format, but not the nice tooling. I rather struggle with inferior open source products and contribute on those than having to go through these 'Google bought us, you have 2 months to export your data' kind of thing.

You can still host it, and pressumably it should keep working, I wouldn't set up a new instance with it because I don't quite see an active dev community around it (But I do with Wallabag or Shiori), no one is stopping the community if there's interest

Around obsidian, as long as you avoid plugins that don't store data as plain text there's nothing to export and you could use any text editor (Or even IDE) in place of obsidian

No boilerplate has an interesting video about it, Obsidian: The Good Parts [1], I can open my Vault with VSCode or nvim and have all my data, sans the pretty views, because I also avoid the non text extensions, and if push comes to shove, I can grep for tags or something simple like that

Obsidian might sell (Maybe when one of the founders/owners go away), but it's not like they have investors to appease, they could keep the show going indefinitely as far as I can tell

Right, I was referring more to the commercial project (similar to Pocket ending). I was testy about it because it was one of the best I'd seen in a while ... until it wasn't. I'm glad it's continued on as an open source, community project.
