The action selling it to another org without that duty is abdication of that duty and they should not have had authority to sell it.
The specific circumstances only make it worse.
Their abdicating stewardship to a group that doesn't have a duty to steward is evidence enough and saying "well they used to" is off topic and not interesting. No need for new arguments when you have none.
and talking about precious years is just off topic and unrelated to the issue at hand.
