There are. Anything that is a file in an open format will outlive me (given minimal care in terms of backups). My family photos, my markdown notes, non-DRM music and ebooks, proper applications. I’d say it’s all digital things, except for a small enshittified sliver.

Renting, however, does not work that way. Any DRM-protected download is a rental. Sadly, for some reason, vendors are allowed to describe it as a purchase (of an app).

I don’t know why you are giving up.
