coupling

Reading wiki page on Dependency injection, the disadvantages section tells this :

Dependency injection increases coupling by requiring the user of a subsystem to provide for the needs of that subsystem.

with a link to an article against DI.

What DI does is that it makes a class use the interface instead of the concrete implementation. That should be decreased coupling, no?

So, what am I missing? How is dependency injection increasing coupling between classes?
