Given the significant efforts that go into fraud detection by financial institutions, I'd say it's not really fear-mongering to suggest that there are nefarious people out there who are trying to get your information so they can get your money.Ah, so we should all listen to his fear-based propaganda - no matter what level of skill you have. Some people are, admittedly, clueless, however, there's that saying "You can't fix stupid."
Though there is risk, if crApple were to allow side-loading, perhaps doing it in a way like Android does, where its not obvious and requires you to figure it out for yourself, would deter the clueless from doing so.
IMO, this is more marketing than anything else. He's saying "crApple is protecting you" and that is completely in line with the image crApple wants to project. IMO, this is not about crApple protecting its customers, it is about crApple protecting its profit - as if that were, in anyway with so many crApple sheep, in danger.
Actually, I think its more about marketing and making people think that owning some brand or product gives them something that they cannot live without or that keeps them safe.
If you have elderly parents then you know that these people are frequent targets of scammers trying to con them out of their money. Scams come in all sorts of flavors and given some of the breaches occurring at major corporations or government agencies, I'd say it's not just the clueless who are at risk.
The iPhone is a consumer product and as such is used by lots of consumers who are not nearly as technical as the crowd here on TechSpot. Even though I am technical and smart enough to avoid most of these attacks, it is nice to know that some efforts are being made to reduce the potential attack vectors.
PS - there's nothing wrong with being motivated by profits. We are all motivated by profits. A profitable company is better for its consumers than a failing company that will be out of business and completely unable to help its customers.
