Apple represented in rather impressive fashion at San Francisco's 44th annual Pride Parade on Sunday.
Tim Cook himself tweeted a photo of 5000 Apple employees and families marching in the Parade. Tim Cook was not one of those marching, but he did hang out beforehand and pose for a number of photos with those marching, even wearing a special tshirt with a stylized Apple logo that says "Pride" underneath it. That same logo was on the iTunes cards the Apple group handed out along the parade route that were worth a free song on iTunes.
(Reminder here about how Tim Cook has not publicly confirmed or denied any sort of tendency.)
