For those that don't know what is going on, here is the backstory: Carl Icahn has recently bought a bunch of ebay stock. He has claimed the company is mismanaged. He has also personally attacked Marc Andreesen. Here is the accusation from Ichan: 1) Marc Andreesen was/is on ebay's board. 2) While on ebay's board, Marc bought most of Skype from eBay. 3) He flipped Skype to Microsoft in less than 2 years, earning himsel…
I think Marc Andreessen position is weak in this fight. I have absolutely no empathy for Carl Icahn, but on this issue, he's got a good point. It seems Marc Andreessen had a conflict of interest and instead of showing that wasn't the case, Andreessen decided to attack Icahn for stuff that aren't related to this issue, even if they were definitely questionable.
As for Andreessen's motive, I suppose he probably thinks Icahn is making a power play and is more interested in fending off Icahn than in defending himself in this particular instance. Icahn clearly wants Andreessen on the defensive, so it kind of makes sense, though it all feels a bit embarrassing.
