Good for the heirs that they get some money, but it is a pity that the collection will be scattered and eventually probably sold at auctions. I didn't find the late counts decision to put things in a foundation that odd. Sadly he didn't put it in a family foundation which would have made much more sense.
I agree that a family foundations would have made a better decision, and probably would have avoided much controversies. But on the other side I think to the (bad) relationship of the late Count with (many of) his children and it isn't a surprise that he didn't do and didn't care of how much they would inherit.
