There are broad parallels to be made between the ETH / ETC hard fork and the HIVE / STEEM hard fork.
The use of a hard fork, combined with moving the community and devs to the new chain, is a strong last line of defence against blockchain attacks when other possibilities are exhausted.
There's probably a lot of affinity for Hive from Buterin for this reason.
You are right, he does mention community but security cannot be overlooked. As a defense against any outside threat, financial or cyber, a fork is how we can take corrective (or responsive) action.
