I think self-hosting has the expectation of the ability to self-host for indefinite period of time. E.g. I can run Jellyfin 10.10 for as long as I have the hardware and willingness to run it. A proprietary piece of software, say Plex, could technically allow that too, but that’s much less likely. Since I can’t see its source code, I can’t know if there’s a time bomb that stops it from working at some future date. Or an update/remote procedure I don’t know about that asks me to pay $750 at some point to continue using it. Which could preclude me from being able to continue self-hosting it. Is the ability to self-host indefinitely an expectation everyone shares? Probably not. Probably worth thinking about in this context though.
