>they let people read their articles for free? This is puzzling to me.
That's the data use consent part...which the article talked about:
>We see a handful of large platforms harvesting users’ private data to share with commercial brokers
>On many platforms, we are no longer the customers, but instead have become the product. Our data, even if anonymised, is sold on to actors we never intended it to reach, who can then target us with content and advertising.
...hence irony. Guardian is either pay or agree to data use
Consent or pay or decline on this particular platform. Since things do have some value. You're reading an article by a human on a platform with content (exclusively?) researched and written by humans. There's a reason the guardian often has articles reaching HN where other "news" outlets do not.
