That's a bit different since those are separate chunks of content rather than running prose (and they're mainly meaningless marketing fluff anyway). I don't find it all that annoying compared to the original article.

It's still incredibly insulting to waste the user's time trying to force them to read the page sequentially instead of being able to immediately scroll to the chunk of content they are actually trying to find. Especially if it is not the user's first visit to the page.

Studies show that viewer comprehension is strictly worse for presentations that use “build” animations vs ones that do not.

I assume the study results would be the same if they were repeated using fade scrolls.

It's not as bad because it's a much faster fade in, but I still find it incredibly obnoxious.
