This mean FTX has a bad security and the team can't make a quick decision to freeze the ETH before the tokens arrived on the hacker wallet, but ETH CEO e.g. Vitalik Butterin and his team should be blamed too. Actually ETH is a centralized token, so it's possible for the CEO to freeze the token even though it's on non custodial wallet. This is why I never trust centralized exchange and coin, they can wrongly freeze someone coin and they're not using their power to freeze the hacked coin (which they must do).
