Though to be fair, on desktop at least, I don't think the site breaks modern web conventions in any egregious way which compromise UX. In most critical respects it works like any other website: it scrolls normally, it has headings and subheadings, it links off to pages located at different URLs, and those inner pages have reasonably conventional layouts. I agree that the mobile experience is broken. They should rethink the layout to add the summaries back onto the main page. If I was offering advice to the designers, I would suggest they abandon the obsession with 100vh layouts and always have a little bit of scrollable content peeking in from the bottom. 100vh layouts evokes the slideshow metaphor, which changes how people expect interaction to function. I would also restyle the "LEARN MORE" buttons to make them clearer. My brain somehow completely ignored them on first viewing. I saw them on subsequent viewings but the low contrast makes them not seem very clickable, I think they could be easily misinterpreted as shortcuts to the next content "slide".
