I use a self-hosted s3 compatible object storage for cheap storage of Android apks and logs. I do push various processed items to Digital Ocean Spaces, so having the ability to use rclone / the same functions for both is useful.

The article didn't load for me (HN hug of death) so I was confused too as are many others in this comment thread (and some have been downvoted for simply asking). Just use the correct terminology; if you're in tech you know there's no room or excuse for ambiguity.
