Marc Andreesseen

Billionaire investor Carl Icahn and eBay are engaging in a public war of words that was ignited by an open letter Icahn sent to eBay shareholders yesterday. In the letter, Icahn accused eBay CEO John Donahoe of ignoring conflicts of interest on its board and called for the company to spin off PayPal. Icahn also disclosed he now owns 2.15 percent of eBay's stock. The letter specifically alleged that board member Marc Andreesseen has personally gained by purchasing large stakes in former eBay subsidiaries and advised and invested in direct eBay competitors Boku, Coinbase, Dwolla, Jumio and Fab.
