I think it's fairly obvious the poster meant that as in that kind of behavior, that takes power away from the user as opposed to exactly that particular reason.

ADB is also much less flexible. I have Titanium Backup making nightly backups, and then FolderSync automatically pushes them to a SFTP server I run. If something should happen to my phone, I'll lose one day of data. This is all automatic, so I don't have to think about it. A backup like ADB that requires manual intervention is likely to be only done irregularly, and Murphy says that you'll lose your phone just after forgetting to make a backup for weeks. Being able to do this is the only reason I bother to root my Android.
