Exactly. The point of moving to the cloud is that your are giving your data to company X, company Y, etc. Of course, both company X and company Y would like all your data, so company X will make super hard to move data to company Y and vice versa. So you are stuck.

And cloud services are mixing "storage service" and "software as a service" so in order to use service of company Z (like project management or something like that) you need also give data to company Z. Which is hard because your data is with company X.

Long story short: I also fucking love the cloud: we kinda went backward in time.
