This zdnet article made such a claim:

I think it's just a case of a journalist trying to make comprehensible 
with that Zope 3 interfaces do.

That or Stephan Richter didn't explain it very well. :)

Interfaces are just annotations for classes and don't change the dynamic 
typed nature of Python at all. Interfaces do allow for powerful 
introspection (which the component architecture builds), and they also 
function as API specification.
