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.
