I don't know what you're on my case for. Are you implying that if the ETC officials ran more nodes, that this attack would not have happened? If so, you are 100% incorrect. Such fully-validating non-mining clients are powerless to stop rollback attacks made by overwhelming hashpower.
Besides, I run a fully-validating non-mining client. Several in fact. However, I am not under the widespread delusion that this provides the system as a whole any benefit.
Fully-validating non-mining clients got segwit shoved through, albeit indirectly.
