Vitalik: Not only because of the theft, but also because many people lost a lot of cryptocurrency

Vitalik Buterin, co-founder of Ethereum, warns that there are still many people who have lost large amounts of cryptocurrency through loss rather than theft. Software bugs, forgotten passwords, lost devices, paper wallets that burned in the Los Angeles fire, not backing up data when upgrading devices... these situations can all lead to losses.
Since there is no attacker to pursue, the victim has no strong need to talk about it.
