Everyone wants to do Apple-like product pages, and no one knows how to do Apple-like product pages. (And in fairness, Apple has forgotten how to do a proper product page, too).
A little more than a decade ago when parallax scrolling was new and seen only on a few websites like apple.com, there was a wow effect. Nowadays apple.com and clones are among the most obnoxious and tiring ad-free websites out there.
Do not hijack scrolling. Use CSS scroll snap if you feel like it, but don't do anything beyond that.
(To be clear, this comment is a tangent — TFA doesn't hijack scrolling. I see the same hilarious 0s everywhere effect though.)
