Because people have lives to get on with. People need to use computers. People have better things to do with their time than spend weekends learning about the details of internet security. It is an elitist position to say that protections erode freedom. In my ICE car the engineers have specified the grade of oil that I need to use. Certainly if I knew the details of the engine, the weather it will be used in, and other factors I could choose alternate oil grades. Are my freedoms being eroded by grade of oil being mandated?
