Serious question, why post something for discussion if it's behind a paywall?
Anyways, here's the relevant excerpt from the HN FAQ
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.
An example of how to get around the Economist paywall is already elsewhere in this thread.
Not true; it has long been customary for people to share paywall workarounds in the comments, and the moderators welcome/encourage it.
But some sites like The Information now have paywall passthrough arguments you can add to the URL, and they seem to be fine.
