That's an answer to a different question. If WSJ, an amoral business entity, decides to serve different content to Google users and different content to everyone else, then you're left answering a question about user intent.
Personally, I don't think it's fair that WSJ simultaneously demands money for content but leaves open a loophole so they can get Google exposure, and then complain when people use said exposure. It smacks of wanting to have their cake and eat it too.
The entire point of the Google link and the whole paywall circumvention is so they can get traffic to their site, right? This implies that getting people on their site is more valuable to them than locking their content behind a paywall.
They could always serve only a summary to both Google and to nonsubscribers from other referrers, but this leads to people mentally filing them in the "useless link, never click" bucket along with Experts Exchange and other crappy content farms.
Actually, Google requires free article access from referrals to be included in Google News at all. (There are other ways, but I think that one was recommended.)
