It's a template called Porto available for 16$ at themeforest. They also forgot to change some default pictures: http://themeforest.net/item/porto-responsive-html5-template/...
Unless a "designer" "developed" the website for them and they got blindsided, which I'm sure happens more than I care to understand. I've seen it happen at well-funded companies — employees claiming they designed something, management had no idea they didn't really do much work at all, etc.
BTW I think they did quite well. I especially like the "live activity" box at the footer that shows recent changes.
Replacing that with a commercial template doesn't seem very FOSS to me.
