It seems you can eliminate all references to googleapis.com by either using a custom font, or using a font that is so widely available it doesn't require download, like Arial. I just tested the site with my friend in China: when using a font supplied by Google, like Open Sans, it takes a full three minutes to load in China. After switching to Arial, it loads near instantly.
