In my mind there's definitely a parallel to bitcoin self custody. Use LibreOffice, and nobody can take it away from you. Your file is on your own system, and nobody knows it's there. You open the file and edit it, and it's nobody's business but yours. There is no tracking, no censorship. Even if your internet provider cuts you off, you can still work on your files.

I realize this is all rather absurdly banal, but this is one of the thousands of faces of digital self-sovereignty.
