The consumer pricing structures, when you start getting services like Dropbox used extensively in professional settings, such as graphic design for advertising, is a problem. When we've got to go back to the original files with a press deadline that's​missed at a cost of tens of thousands of dollars, where do we expect to find the customer service, if we're impacted by a degraded node in Dropbox's cloud? I accept the problem is with the community of freelance designers, and equally the disinterest if agencies and other line of business data consumers to provide adequate alternatives (we do, with real enterprise grade systems and support contracts) but even Draconian measures to enforce control only back up a community who have been backed up and disenfranchised plenty enough by the large agencies pushing work off the payroll for the length of my career (decades...) and it just happens to be a hard sell to make any extra work for a highly talented community who are now treated as least cost providers.
