I am pretty sure he wouldn’t do a chain rollback just to recover one theft. It would pretty much destroy the coin and this is what happened back in 2016 with the DAO hack.

Basically it almost destroyed the coin because it went from decentralized state to a centralized state. This is the reason why ETC exists today. Those stolen coins are still circulating on the ETC and the hacker sold off a small percentage of them. So tweeting him won’t get anything done but might spread awareness of the ledger phishing attacks to prevent more thefts.
