Norton is very heated in the comments here. But even separating this concern.
Personally, the landing page itself hurts my trust of the goal.
Why?
When we think of a browser, before anything. We want something that feels snappy and performant. Even if the browser IS snappy. the fact that this page feels unresponsive in a way on my MacBook Pro M1 Pro. already raises concerns of performance.
For my sanity, I've tried Vivaldi's website, Brave's website. All feels "light" and scrolling is a breeze on Safari.
Those are just my few cents, but I'm pretty sure others might feel the same when making a landing page for any product where it should feel responsive.
