Right click on the page, "inspect element". Break that out into its own window, if you haven't already. Switch to the "network" tab. Reload the page. Click on the first entry in the list (antiwork-reddit.html). Click on the "response" tab on the righthand half of the dev tools window. Read it there.

This works for all paywalls where javascript immediately refreshes the page to show very little. Some/few show that from the beginning (WSJ I think?), waiting for you to log in to actually read it.
