They're not posting that article in full because they're making money from it or taking credit for it. They're posting it because I can't read the article you submitted. I can't comment on your post that you didn't even bother summarising without buying a subscription to The Atlantic and Lemmy isn't a website for Atlantic subscribers.

When I moderated subreddits and people posted full articles, nobody batted an eye on a corporate website full of neoliberals because even they understood it's a basic public service. If that post is supposed to be anything more than a headline, people need to be able to read it to engage with it. And that's reddit. This is specifically a project that rebels against that corporate control and you're that devoted to someone else's profits. Presumably not your own unless you work for The Atlantic, but for someone else's business that had almost $100m in revenue last year.

Why else would you make your own post unreadable in your own subcommunity unless 𝔢𝔫𝔣𝔬𝔯𝔠𝔦𝔫𝔤 𝔱𝔥𝔢 𝔯𝔲𝔩𝔢𝔰 filled some hole inside of you? What else would this possibly achieve on a website where almost all other paywalled article posts have a comment helpfully allowing people to read it? The alternative to it being pathological for you is that you're stupid.
