Threadless is a t-shirt company--anyone can submit designs, which are then voted on by the public, and top vote-earners are printed on shirts, hoodies, bags, etc. I believe the survey is referring to applying that sort of community model to bike helmet designs.

Also note that it says "If you'd like" to get updates, to share your contact info--doesn't seem like that's mandatory to participate in the survey.
