Couldn’t they just have the app ask for the user’s API key? I use a weather app that does that with OpenWeatherMap.

Yes. They have already done this to r/adviceanimals and threatened to do it to r/pics. They will be doing it to any subs that don’t go back to public. It is time to leave reddit permanently.
