Hmm maybe you are using Go Daddy Managed WordPress hosting and not standard Go Daddy hosting? The link below contains a list of blacklisted plugins that are not allowed on Go Daddy Managed WordPress hosting. BPS is not currently blacklisted on Go Daddy Managed WordPress hosting, but since we added DB Backup to BPS then maybe BPS will be blacklisted at some point on Managed WordPress hosting. I think they are primarily blacklisting these backup plugins because they do file backups so maybe BPS will not be blacklisted on Managed WordPress hosting since BPS only does DB Backups. ;)
It looks like Go Daddy Managed WordPress hosting is blacklisting these plugins for a few reasons that they have stated below.

"Duplicate Functionality - Backups
These plugins duplicate our existing backup and restore functionality. We have seen these plugins cause problems for customers because they use too many resources creating archive files (tar/gzip/zip) and we have seen some poorly configured plugins create recursive backups and sites exceed their allotted storage amount.backupwordpress
