I hear you man. I think there have been a few divorces to pay for!
I think the money has not been wasted but they keep a staff which spends much time looking at the vast archive FZ left behind which needs to be carefully assessed and lots which need remedial attention, stuff like baking tapes readying it for a one time deal for duplicating before it disintegrates. Stuff like that. Money can be quickly inhaled I believe. Its only recently that Dweezil has been touring with his fathers music lest it disappears with people of my generation and older. FZ died 19 years ago today/yesterday.
