To flip the scenario: How would you feel if Jack Ma had bought Yosemite in 1991, set up the valley as a private retreat, lived down in the Ahwahnee until his death, and had his widow donate it to the federal government?

If the government had never set aside Yosemite as a park, and it had been private land that Jack Ma bought, I would be thankful for him to donate it.
It would be terrible conservation policy to rely on private individuals to donate land. But if people do, I would be thankful.
The fact that Jack Ma is a Chinese national feels like an irrelevant distraction. Why would that affect my gratitude?
