I almost automatically closed the tab because it looked like a paywall. Why do I have to click "Show full article" to see the article on the page for that article? O_O
I vaguely remember implementing this exact thing for at least two clients, and if remember correctly the reason is that such a 'show full article' button allows anything 'below the fold' (meaning the button) to be more prominently visible.
It's a rather ironic that I had to turn off my uMatrix filters to get the full 'experience' of that button.
