On the contrary, many (including myself) would argue that "the victim's amount of money/power" has absolutely no ethical relevance: "You shall do no injustice in judgment; you shall not be partial to the poor nor defer to the great, but you are to judge your neighbor fairly" (Leviticus 19:15).
But some would argue that reducing the amount of resources and power available to someone who has immense amounts of both and is causing great harm to society as a whole - is ethical.
I'd argue that the moral principles of the Levitical law (e.g. "adultery is wrong") are not inherently bound to the specific punishments (e.g. "adultery is a capital crime") prescribed for ancient Israel.
Unfortunately my details (address, bank details, government IDs) have been leaked a handful of times now because companies that I do business with have been hacked. Each time the company involved has faced practically no real penalty aside from a minor hit to their reputation. Your moral obligation isn't to Sam Altman, it's to his customers, who are real people.
