Too late? I already lost a ton of data in the covid purge. (was active user of /r/NoNewNormal) Every comment, post or interaction on a banned sub is suddenly deleted permanently with no way to retrieve it. That's really losing data, not a made up crisis of "enshittification."

Most people worried about the API change have the "correct politics" so your data is safe. It's only people who participate in wrongthink that need to backup everything.
