> So how can one claim the hardfork fixed a protocol bug?
If I understand it, it isn't fixable without affecting every existing contract, so, the best fix was to patch the problems it caused, patch Solidity, introduce safer opcodes that avoid it, and invest heavier on security, which is exactly what was done (just see how much the EF is spending on security-related grants...)
