The NYT paywall is generous to subscribers and non-subscribers alike, and the NYT has managed to keep both goodwill and traffic with respect to its non-subscribers. That can’t be said of the WSJ and FT, who take a much more hostile and adversarial approach to the people who aren’t paying them hard cash. The NYT sees value in remaining accessible to everybody; the FT and WSJ see value in restricting access only to paid subscribers.
Which is why I think it’s fundamentally misconceived to think of the FT paywall as being very similar to the NYT paywall. Rather, it’s at heart the same as the WSJ paywall: a way of restricting content as much as possible to subscribers exclusively. The NYT is a free website with a mechanism for getting readers to subscribe; the FT and WSJ are subscription websites with some content available for free. It’s the NYT model which I love, not what’s going on at the FT.
