Just add this script as a bookmarklet (drag it to your bookmark bar) and click it whenever you get a paywall message:

javascript:%20window.location%20=%20window.location.protocol%20+%20'//'%20+%20window.location.hostname%20+%20window.location.pathname%20+%20'?partner=rss&emc=rss&smid=tw-nytimes';

PS: Support journalism if you have the money to do so!
