The key line is actually this:

>An application that adheres to the REST architectural constraints may be informally described as RESTful, although this term is more commonly associated with the design of HTTP-based APIs and what are widely considered best practices regarding the "verbs" (HTTP methods) a resource responds to, while having little to do with REST as originally formulated—and is often even at odds with the concept.

Taking that to mean you disagree. However using HTTP verbs has nothing to do with using JSON or not. Notice it says "HTTP" not "HTML" APIs.
