Why is there always someone commenting an archived version of an article

If you're asking why sometimes people post, e.g. 'https://archive.md/oE13T', as single comment (example https://news.ycombinator.com/item?id=29012142), that's a work-around for paywalled articles. Usually somebody will ask (or complain) that the article is behind a paywall, lately users post the work-around even before somebody asks.

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. More here.

For the benefit of people who don't pay for a subscription to The New York Times or whatever.

People aren't supposed to do that, but they still do. People have tried flagging articles from paywalled sites, which is also something you're not supposed to do.

I have no idea how "archive.md" does what it does and doesn't get shut down.
