If it works against the user's intention then I'd say that's friction of another sort. For example if you go to a website and scroll more than you wanted to due to dark UX (as opposed to good content), the user may not immediately realise it's a bad experience for them, but still they've wasted extra time hence the site has got in the way of what they were originally trying to achieve. It's become normalised so it's not always recognised.

On a personal note, I want to be able to go on Lemmy and say "OK, I'll read the top 2 pages of my subscribed communities" and let that be it, that's a much more reasonable way of approaching a large amount of content.
