I think the real problem is that cloud services relieved some of the pressure to invent standard file formats. And then greedy companies wanted to be walled gardens, rather than integrating with each other. But when propriety cloud services WANT to work together, they need to come up with standard file (or stream) formats. When they do, integration is often not that hard.
