Are folks who write about phoney cures legally liable for the deaths that could be prevented by scientifically proven methods? I'm not sure it's been tested in the courts.
The problem is hidden malware in firmware in devices like hard drives. No computer manufacturer can be immune to that if they buy parts that are infected when intercepted during shipping between the manufacturer and the computer assembler or end user by some three letter agency. The same for the finished computer. And what about malware hidden so deeply into computer parts where the firmware can't be rewritten? If Intel's or AMD's parts are corrupted in this way during manufacture, swapping out the part will never solve the problem.
