Dropbox used to be hosted on AWS.

How is a laymen supposed to tell the difference between Backblaze - running their own servers, and a Dropbox-like - which is really just uploading your files to amazon's servers?

That's the point I was trying to make.

Assuming Dropbox encrypt the data at rest, Amazon won't have any access to it. And if they do delete stuff they now have to deal with a company instead of single individuals.
