I'm in China atm, which is probably an area that Stripe would want to target with both atlas and connect (there's a ton of marketplace/ecommerce sellers based here, and a lot of tech innovation), and both those sites take a stupid amount of time to load.
That animation also destroys my mediocre laptop.
The pages look nice and are rich in content, but those animations and all the superfluous fonts and stuff cause them to be almost unusable if you're not on reasonably new hardware with a reasonably fast internet connection.
