I don’t really understand this viewpoint - scrolling has always been the default way to see more content on a webpage. Clicking on things to navigate is very much a secondary activity. Why would you not scroll every web page to see if there is more content that didn’t fit on your screen?

I suppose because modern websites are actually apps, in an app you click on stuff to see more content

If web page does not look like a blog or a newsletter, it is not wrong to assume the app format
