Do you use music player? Most, including open source are using SQLite inside. There are open source tiling maps formats like MBTiles, based on SQLite. Just dig around, you can find plenty of examples. It's other way around since database format is well known with tooling available

I’m not remotely claiming ‘I never use software that has SQLite inside it’. I use loads of programs that do. And that’s precisely the kind of walled garden I’m talking about.

Keeping your playlists in a specific music player app’s SQLite database forces you to use that app to search or delete or share those playlists. Heck, some apps use SQLite blob storage to store images or even music files.

Open software should use open file formats and store data in the file system where other programs can access it.

That's what SQLite is.
