Apple’s marketing materials use Myriad. It would make no sense to set their marketing materials in San Francisco. That would be totally inconsistent and weird. (Also, this is just a download page for people wanting to work with the font … not a place to show it off. I mean, if this were a place to show it off then setting that in San Francisco would still be wrong, wrong, double triple wrong. You would set the text in Myriad and give examples of San Francisco.)
