Nobody said that you shouldn't have any data in the cloud. The argument is that you shouldn't have your data only in some cloud.

If you have your data in some cloud (either directly or as backup) as well as in your really crappy backup solution that has a 10% failure rate, you still are ten times less likely to loose your data than by just keeping your data in the cloud.

It seems like storing your backups using two cloud providers is much more reliable than using just one cloud provider + local NAS.

As long as - if this is a company - different people have access to those accounts, yes.
