It a pity but it is far too easy to blame it just on the rules and regulations. The people who maintained this aircraft are nearly all former Royal Navy Technicians and most/all of them are on the mature side of 70. It proved to be very difficult to find qualified volunteers, who could maintain the Catalina, outside this former navy group. And where the Dutch Royal Air Force Historic flight foundation has full support from the Royal Netherlands Air Force, the Royal Netherlands Navy wasn't interested in the Catalina at all. Without their support it was hardly possible to maintain the Catalina in flying condition.
Its sad to see such a beautiful aircraft go, but I think the Catalina group did wise to sell it to the Collins foundation. At least they are sure the aircraft will be looked after very well and will be kept in flying condition. And according to the opinion of the person from the Catalina foundation I spoke with: "Due to its remarkable service history during the war, this particular Catalina really belongs in the US".
In another thread SH427, who works for the Collins foundation, told us that the PH-PBY will be restored in wartime configuration.
