I understand what you're saying and in most cases, most companies, most products, you are correct and I would absolutely agree. In this case it is an IOS zero-day. I'm not sure of the number of people on the planet using IOS but the chances of that zero-day being applicable to the phone in your pocket at one point aren't too bad. I do think Apple should be held responsible, their massive amount of sales has given them a massive amount of responsibility that they are not stepping up to.
