iOS is genuinely terrible. I appreciate the point that so is web design for many sites, but even if you ignore that, 97% of bugs on our product with no cookies, ads, analytics etc come from iOS. My favourite time burner right now is when apple pushed for new viewport units and then don't respect them. Their address bar animated design is atrocious.
iOS comes with the setting to open every web page in reader view by default, which kills all ads, cookie popus, autoplaying videos, sticky headers, etc.
It's not hard to design beautiful and usable websites, which works on all devices from the past 10-15 years.
Wanted to say something similar. It's really effective to bring home how stupidly massive this thing really was. You just keep on scrolling and scrolling and the little bombs don't end!
