This seems to be more of a philosophical stance than an argument based on outcomes. It's also a call to think before knee-jerking "the cloud". And I do see the philosophical argument it has merit. But it does lack a business argument [for service consuming businesses] which will win out in most cases.

In other words, in real world usage, the cloud is more dependable and flexible than internal IT infrastructure providers, for most businesses.

That said, there is a good philosophical argument against the cloud.
