Yes, I get that this adds value on top of Backblaze (e.g. Dropbox is not just rsync), though even then, usually services that resell or build on top of an established commodity product (e.g. storage) model their own pricing models off of the underlying commodity, which is why I was surprised.

But I didn't realize that Backblaze B2 had a completely different pricing scheme. This makes more sense now.
