A lot of web "design" is about how it looks rather than how usable it is. At no point any stakeholder stops and actually uses the product, they scroll up and down, enjoy the pointless "scroll in" animations and say "kewl". Never mind the text that is at 50% opacity until you scroll to the exact intended point, because nobody actually attempted to read it.

Actually that's exactly what they do. They like the animations while some people, especially devs, do not. But they don't use it multiple times, because they would be able to see how it gets annoying after the first time.
