(Reuters) - EBay Inc said it has sold its 28.4 percent stake in Craigslist Inc back to the online classified advertising company. Under a confidential settlement agreement, all litigation between the companies will also be dismissed, eBay said in a blog post. The companies have been feuding for years in civil court over allegations that eBay took a stake in Craigslist and then misappropriated confidential information while secretly planning its own classifieds site.
