I think it's sad when a company and its founder don't get along. That's one of the reasons I counsel entrepreneurs to really get to know the VCs before they take the money. Too often they don't and assume that the VCs are investing in their vision. Later on it's a surprise when they have to fight for the right to do what they wanted to do when they got the VCs backing. I wish Greenspun the best of luck, and hope they get back on track at Ars Digita.
