News Article Content without JavaScript

Curiosity question. I noticed this with Bloomberg but I've seen it with several others: the article content is unloaded if JavaScript is disabled, and not to be found in the HTML or DOM.

A lot of news websites (paywalled or otherwise) still load the article content, sometimes hidden, in the HTML with JavaScript disabled. I've noticed lots don't.

Is this because Google has gotten better at loading the articles when it crawls so gating it behind a paywall doesn't matter anymore for SEO? Maybe there is some access token or element the crawler uses or they give search engines the article content from somewhere else (or don't care that much about losing out on search results if it gets them paid subs)?
