Now Winklevosses Getting Sued for Facebook Money Software developer says he deserves up to 50% of their settlement By Mark Russell, Newser Staff Posted May 13, 2011 10:32 AM CDT 2 comments Comments Cameron (L) and Tyler (R) Winklevoss, founders of social networking website ConnectU, are suing Facebook, and now their former partner Wayne Chang is suing them. (Getty Images) (Newser) – First the Winklevoss twins went after Facebook, and received $65 million for their efforts. Now, a Boston software developer is saying the Winklevosses owe him, and is taking them to court for up to half of that settlement. Wayne Chang says his P2P software was integrated into the Winklevosses' ConnectU website in exchange for 15% of the company, reports the LA Times. Chang also says he then formed the Winklevoss Chang Group partnership with the twins, and that his 50% stake in that partnership entitles him to half of their Facebook payout. "Chang alleges that he has received nothing in return for the substantial benefits he provided to ConnectU, including the value of his work, as well as i2hub's users and goodwill," wrote the judge who allowed the suit to proceed. Chang has been pursuing a share of the Facebook deal since 2009.
