Is Macworld cloaking content with Google's OK?

I found this page via a Google search:

http://hints.macworld.com/article.php?story=20050222062346277

The content that appeared in Google's search results is cloaked, and there's a message that says I need to answer a survey question, or share the page on a social site, to view the content.

The "Answer a Question to continue reading this page" widget has a "Powered by Google" stamp on it.

Is Google allowing sites to have cloaked content if they use its widget?
