True, but I can understand Apple&#x27;s position.<p>Commercial software is unlikely to be a trojan. You have much higher value as a paying customer than as a victim.<p>Open source software is similarly unlikely to be a trojan, especially if compiled from source.<p>Closed-source freeware is the perfect attack vector. Opaque and widely disseminated. Who knows what&#x27;s going on inside? Freeware is responsible for a gigantic amount of malware.
