The letter we just saw extracts of was the good thing to do if Jerry wants to avoid being put in jail.

He's legally bound to maximize EXISTING shareholder's value, so he can't just say "I don't want to give you Yahoo".

But he can say he expects more details, and can provide a valorisation of Yahoo that seems reasonnable (as in "explained, however weirdly") to ask Microsoft to give more or go to Hell.

It'll probably only postpone the inevitable though. Yahoo is probably worth less the those 44 billions, and whether it's a good deal for Microsoft or not is moot, since it's microsoft's (and the world's) problem, not Yahoo's shareholder's
