I think it's absolutely great that they've donated all the proceeds to Wikipedia :) Congratulations. It's heartwarming to know that although there are some free loaders, you were still made a pretty penny. On the other hand, how come all the design work, copy writing, etc are considered free? That's just masking the actual cost of the product.
Looking at their quirky web page of comparisons, I think it would be hilarious if the wikipedia deletionist camp responded by deleting all the articles quoted on their page. I'll never donate a penny to wikipedia until that social problem is eradicated. "Here's $70K of value... whoops deleted"
