I'm not sure how far the talks went, though given that this is just coming out now, I'm guessing they didn't go very far. Would be interesting to know if the offer is still actually on the table like the article hints at.
This is the price you pay for giving up all voting rights. If Evan doesn't want to sell no sale, no matter how good of an offer is on the table. With voting rights atleast someone can hold the CEO's feet to the fire to make them consider the idea.
