Hey, remember how a few years ago, Kickstarter changed their rules to require that all hardware projects funded through the platform actually exist in a working form? Late last night, Kickstarter enforced that policy on a campaign that had already raised $4 million. Kickstarter administrators apparently didn’t believe that the product, which promises a “shaving revolution,” exists yet as promised. Kickstarter’s rules dictate that a new product must have a working prototype.
