I realize they are also using Google's survey product. I don't see anything on that site that indicates cloaking like this is acceptable. What makes you think that?
Edit: Thanks for the reply. I agree they're saying that the survey product can be used in place of a paywall. But popping up a paywall is still cloaking. There's no indication that this grants you an exception.
I always thought that was against their policy but so many major sites do it.
@rgbrenner: I think that only shows up when you come from the Google search page, a normal link will just show the paywall with no option to bypass it.
Are sites allowed to show Googlebot the full article but show a paywall to everyone else? I think that's what was meant by cloaking.

paywalls are offensive
