in the case of a liquidation (if the FSF went bankrupt), the successor could close-source all of the GNU code, because it all belongs to the FSF.
Is that really likely?
In any case, even if the FSF were somehow completely taken over, wouldn't there still be the problem of breaking all the contracts the FSF has signed with copyright assigners? I seem to recall their standard assignment agreement including a clause where the FSF promises that the licensing of the code will always be "in the spirit of" the GPL, or something like that.
I doubt the GNU stuff is really at any more risk of proprietary branches than is Linux.
