I didn't write that it's exclusively her fault. If it wasn't her, it would've been another captured developer, so obviously her employer is at fault as well. You are still responsible for your actions. If I were offered to pilot an airplane but knew I wasn't qualified I'd decline the job offer. If I accepted the job offer and crashed the airplane because I'm incompetent, would my employer be exclusively at fault, or would I carry some responsibility as well. The same applies to ruining a mission-critical project such as Bitcoin. You aren't absolved of responsibility because your employer offered you a job without you being qualified. And as I already wrote, it is mostly our own fault for allowing ~100% of nodes to run a single implementation for so long. View quoted note →
