BTW, is a charitable organization that exists on donations allowed to go on strike?
Why wouldn't it? Wikipedia can shut down today without any legal consequences. The only legal concern is that they'd have to ensure that any residual property held by the Foundation after it ceased in the furtherance of its charitable purpose was properly conveyed to some other charity or escheated to an appropriate governmental unit. (Well, actually, any restricted gifts would have to be refunded. But the Foundation receives fairly few restricted gifts.)
