There are plenty of ways to bypass a paywall - if you’re on HN I trust that you can figure it out.
From https://news.ycombinator.com/newsfaq.html: “Are paywalls ok?
It's ok to post stories from sites with paywalls that have workarounds.
In comments, it's ok to ask how to read an article and to help other users do so. But please don't post complaints about paywalls. Those are off topic.”
