Use Firefox Reader View after the page covers the content with the article limit banner. Reader View is an icon that appears on the right side of the address bar.

Even better: These extensions let you open the page directly in Reader View, the 1st via context menu, the 2nd via list of sites to be always opened in Reader View:

https://addons.mozilla.org/firefox/addon/reader-view/

https://addons.mozilla.org/firefox/addon/automatic-reader-vi...

I got caught by a dark pattern asking me subscribe with an x to close option. Clicking the x option navigated me away and then informed me that I'd reached an article limit when I tried to go back to the article.

That happened to me as well.

Try opening the page in a private Firefox window. That worked for me.

Disable js. Works fine in Brave after you block scripts.
