In the court battle between Internet titans eBay and Craigslist, the tables were turned Wednesday morning as the lead lawyer for Craigslist attempted to effectively put eBay on trial with a withering cross-examination of an eBay in-house lawyer.

And eyebrows were raised in the afternoon when a top eBay executive testified that he considered it tantamount to “extortion” when Craigslist’s two founders demanded that they be paid $16 million as a condition of approving eBay’s purchase of the stake held by a third founder who was leaving the company.
