I’m pointing out that the DAO hack transactions are not muted on ETC, they still exist as transactions in a validated block on that chain. Whether its state of mutability exists in binary or on a spectrum, ETC is shown to be immutable using your criteria, further showing that it’s not as simple as “crypto isn’t really immutable”. Different chains, even directly originating from the same project, have different characteristics with respect to mutability. It’s not to say that ETH is worse and/or better than ETC, or that either of them are good, it’s just what’s been observed as a matter of record, contrary to your depiction
