Pretty much any electron app you download is probably tied to a backend and will fail if their servers go offline. It is kinda sad. Electron apps are usable as long as the company is really iterating forever.

Is the real problem that we're overemphasizing UI and React and UI frameworks so much that we're now just really focused on building really pretty apps that have little or no long term usefulness? At this point it feels like full Companies are just Apps and those companies make something that fills exactly one need, like renting a broom from your neighbor. And it's really pretty and they had the best lawyers in the world thinking about all the potential legal nightmares of neighbors renting brooms that it really is a great app, should you ever need to rent your neighbor's broom. Or you can walk over to your neighbor and borrow it.
