Is this basically saying he sent all the ETH out of his "account" (presumably to another one that was pre-generated & pre-shared half the private key with his family), so that it just had the Shiba tokens left in it?
Then he didn't have to worry about the Shiba related transactions affecting his ETH?
He didn't want to have the signal be that he was happy holding SHIBA and was uncomfortable with that much power & control over SHIBA. So he wanted to be able to transfer his SHIBA out to a hot wallet and then burn most of it and donate the rest, given the amount of money involved he took extra steps like buying a new computer to generate the new keys, airgapping it from the internet while it held the cold wallet keys etc
