I do have to question how it's profitable for most of these companies. I use BackBlaze for my own computer, and it's like $60/year. It would cost me more money to buy a single HDD of the appropriate size, and BackBlaze has hashing/encryption and redundancy. So maybe what, 80% storage efficiency, and then even just double-redundancy, means I have to remain a customer of theirs for several years just for them to recoup their hardware costs (I don't care how many HDDs they buy, we're still talking several $$ per TB).
So unfortunately, I see this as a continuing trend. Consolidation, and then price raising.
