it’s amazing the strength of opinion about this for either point of view

Regardless of user preference, on the web it’s a fool’s errand to try to force your content into a page-by-page format. Designing a paged content presentation that’s guaranteed to work on every device with every screen size is so close to impossible that it’s not worth bothering. And that’s before you take into account whether or not the user prefers to view in landscape or portrait, what aspect ratio their screen has, what zoom level their browser is set to, or even how their browser implements zoom and content rescaling. So 9 times out of 10, you’ll wind up with your content being broken into pages that the user still has to scroll around in to see all of anyway. Or where everything will be illegibly microscopic. Or both! Especially if they turn up on a mobile device – which something like 92% of all web users these days.

The greatest driving factor behind sites breaking articles into “pages” is so they can load more ads on each page change.

(This does not apply to non-website mediums, obviously. IDGAF how you digest your e-books, manga, or whatever.)
