I don’t see any problems with that. Even I (and probably most others here), who are FOSS advocates, think Obsidian’s model is fine.

The devs surely get why FOSS is important, and try their best to match the pros of open source. They even stated that if the company goes bankrupt or they stop developing the app, they’ll open source it.

One major thing they do absolutely right is how the notes get stored. On other note taking apps, it’s a proprietary database, often “in the cloud”, where your notes get hold hostage. Here, they’re just Markdown files, and the whole thing is pretty open, encouraging a strong community.

It’s similar to Valve/ Steam. Proprietary, but liked by most Linux people.
