Refresh while in reader mode. The DOM with most paywalls is destroyed post-render, not before it reaches the web browser. Refreshing in reader mode prevents client side scripts from executing and rewriting the DOM. I'm presuming this is to be search engine friendly, but I'll leave it to the SEO experts to educate me.

This has changed for most major sites. Users behind the paywall are served a "truncated" version of the article that never included a full version of it. The days of "press Esc before it finishes loading!" are coming to an end it seems.
The truncated version is still more SEO-friendly than a blank page as it has the headline and partial content.
