"Who's still left in the home backup solution ring? Besides iCloud/Google Drive/Dropbox, I count...Backblaze? And that's it? "
If you are a unix user and/or reasonably technical, I think rsync.net would be the best choice.
You get an empty ZFS filesystem, possibly with snapshots enabled, that you can do whatever you like with (provided "whatever you like" is something that runs over SSH...).
Pointing borg/rclone/restic/git-annex/etc. to rsync.net works exactly the way you'd think it would.
Looking at rsync.net's pricing system, I calculate that backing up 1TB of data would run about $25/mth. Do you consider that competitive for a home user just trying to backup his photos? I have considerably more--4TB, to be exact, so that seems really untenable to me.
